Going Concern Uncertainties [Abstract]
Going Concern Uncertainties	2. GOING CONCERN UNCERTAINTIES The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the discharge of liabilities in the normal course of business for the foreseeable future. As reflected in the accompanying consolidated financial statements, the Company incurred a significant net loss of $17 million for the year ended December 31, 2018, an accumulated deficit of $6,443,102, an outflow cash of $343,970 from operating activities and a negative working capital of $10,458,105 at December 31, 2018. In addition, the Company continues to generate operating loss and have limited cash flow from its operations. Management believes these factors raise substantial doubt about the Company’s ability to continue as a going concern for the next twelve months. The continuation of the Company as a going concern through the next twelve months is dependent upon (1) the continued financial support from its stockholders or external financing. Management believes the existing stockholders will provide the additional cash to meet with the Company’s obligations as they become due, and (2) management to further implement its business plan to extend its operations and generate sufficient revenues to meet its obligations. While the Company believes in the viability of its strategy to increase sales volume and in its ability to raise additional funds, there can be neither no assurances to that effect, nor no assurance that the Company will be successful in securing sufficient funds to sustain the operations. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. These financial statements do not include any adjustments to reflect the possible future effect on the recoverability and classification of assets or the amounts and classifications of liabilities that may result from the outcome of these uncertainties. Management believes that the actions presently being taken to obtain additional funding and implement its strategic plan provides the opportunity for the Company to continue as a going concern.

Summary of Significant Accounti

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES • Basis of presentation These accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP"). • Use of estimates In preparing these consolidated financial statements, management makes estimates and assumptions that affect the reported amounts of assets and liabilities in the balance sheet and revenues and expenses during the years reported. Actual results may differ from these estimates. • Basis of consolidation The consolidated financial statements include the financial statements of NFEC and its subsidiaries. All significant inter-company balances and transactions within the Company have been eliminated upon consolidation. • Cash and cash equivalents Cash and cash equivalents consist primarily of cash in readily available checking and saving accounts. Cash equivalents consist of highly liquid investments that are readily convertible to cash and that mature within three months or less from the date of purchase. The carrying amounts approximate fair value due to the short maturities of these instruments. • Restricted cash Cash and cash equivalents that are restricted as to withdrawal or use under the terms of certain contractual agreements are recorded in restricted cash account on the Company's consolidated balance sheet. The Company's restricted cash balance is related to a contract performance guarantee bond. The December 31, 2018 and 2017 balances were $179,496 and $0, respectively. • Accounts receivable and allowance for doubtful accounts Accounts receivable are recorded at the invoiced amount and do not bear interest, which are due within contractual payment terms, generally 30 to 90 days from shipment. Credit is extended based on evaluation of a customer's financial condition, the customer credit-worthiness and their payment history. Accounts receivable outstanding longer than the contractual payment terms are considered past due. Past due balances over 90 days and over a specified amount are reviewed individually for collectability. At the end of each period, the Company specifically evaluates individual customer's financial condition, credit history, and the current economic conditions to monitor the progress of the collection of accounts receivables. The Company will consider the allowance for doubtful accounts for any estimated losses resulting from the inability of its customers to make required payments. For the receivables that are past due or not being paid according to payment terms, the appropriate actions are taken to exhaust all means of collection, including seeking legal resolution in a court of law. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers. As of December 31, 2018 and 2017, the allowance for doubtful accounts was $12,269,647 and $760,164, respectively. • Retention receivable Retention receivable is the amount withheld by a customer based upon 5-10% of the contract value, until a product warranty is expired. The warranty period is usually 12 months. • Inventories Inventories are stated at the lower of cost or market value (net realizable value), cost being determined on a weighted average method. Costs include material, labor and manufacturing overhead costs. The Company reviews historical sales activity quarterly to determine excess, slow moving items and potentially obsolete items and also evaluates the impact of any anticipated changes in future demand. The Company provides inventory allowances based on excess and obsolete inventories determined principally by customer demand. As of December 31, 2018 and 2017, the Company did not record an allowance for obsolete inventories, nor have there been any write-offs. • Property, plant and equipment Property, plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses, if any. Depreciation is calculated on the straight-line basis over the following expected useful lives from the date on which they become fully operational and after taking into account their estimated residual values: Expected Residual value Building 30 – 50 years 5% Plant and machinery 10 – 20 years 5% Furniture, fixture and equipment 5 – 8 years 5% Expenditures for repairs and maintenance are expensed as incurred. When assets have been retired or sold, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is recognized in the results of operations. • Land use right All lands in the PRC are owned by the PRC government. The government in the PRC, according to the relevant PRC law, may sell the right to use the land for a specified period of time. Thus, the Company's land purchases in the PRC is considered to be leasehold land and is stated at cost less accumulated amortization and any recognized impairment loss. Amortization is provided over the term of the land use right agreement on a straight-line basis, which is 50 years and will expire in 2059. • Construction in progress Construction in progress is stated at cost, which includes acquisition of land use rights, cost of construction, purchases of plant and equipment and other direct costs attributable to the construction of a manufacturing facility in Yinzhou District Industrial Park, Tieling City, Liaoning Province, PRC. Construction in progress is not depreciated until such time as the assets are completed and put into operational use. No capitalized interest is incurred during the period of construction. • Impairment of long-lived assets In accordance with the provisions of ASC Topic 360, " Impairment or Disposal of Long-Lived Assets • Revenue recognition On January 1, 2018, the Company adopted ASC 606, Revenue from Contracts with Customers, using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC 606, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company's historic accounting under ASC 605, Revenue Recognition. The adoption had no material impact on the Company's consolidated financial statements and there was no adjustment to the beginning retained earnings on January 1, 2018. Under ASC 606, revenue is recognized when control of the promised goods and services is transferred to the Company's customers, in an amount that reflects the consideration that the Company expects to be entitled to in exchange for those goods and services, net of value-added tax. The Company determines revenue recognition through the following steps: • Identify the contract with a customer; • Identify the performance obligations in the contract; • Determine the transaction price; • Allocate the transaction price to the performance obligations in the contract; and • Recognize revenue when (or as) the entity satisfies a performance obligation. • Cost of revenue Cost of revenue consists primarily of material costs, direct labor, depreciation, and manufacturing overhead, which are directly attributable to the manufacture of products and the rendering of services or projects. Shipping and handling costs, associated with the distribution of finished products to customers, are borne by the customers. • Comprehensive income ASC Topic 220, "Comprehensive Income", • Income taxes Income taxes are determined in accordance with the provisions of ASC Topic 740, " Income Taxes ASC 740 prescribes a comprehensive model for how companies should recognize, measure, present, and disclose in their financial statements uncertain tax positions taken or expected to be taken on a tax return. Under ASC 740, tax positions must initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts. For the years ended December 31, 2018 and 2017, the Company did not have any interest and penalties associated with tax positions. As of December 31, 2018, the Company did not have any significant unrecognized uncertain tax positions. The Company conducts the majority of its businesses in the PRC and is subject to tax in this jurisdiction. As a result of its business activities, the Company files tax returns that are subject to examination by a foreign tax authority. • Product warranty Under the terms of the contracts, the Company offers its customers with a free product warranty on a case-by-case basis, depending upon the type of customers, nature and size of the infrastructure projects. Under such arrangements, a portion of the project contract balance (usually 5-10% of contract value) is withheld by a customer from 12 to 24 months, until the product warranty has expired. The Company has not experienced any material returns or claims where it was under obligation to honor this standard warranty provision. As such, no reserve for product warranty has been provided in the result of operations for the year ended December 31, 2017. However, due to limited collection from its receivables during the year ended December 31, 2018 and the subsequent period, the Company reported a reserve of $942,382 for the receivable withheld by its customers for product warranty. • Net loss per share The Company calculates net loss per share in accordance with ASC Topic 260, "Earnings per Share." • Foreign currencies translation Transactions denominated in currencies other than the functional currency are translated into the functional currency at the exchange rates prevailing at the dates of the transaction. Monetary assets and liabilities denominated in currencies other than the functional currency are translated into the functional currency using the applicable exchange rates at the balance sheet dates. The resulting exchange differences are recorded in the statement of operations. The reporting currency of the Company is the United States Dollar ("US$"). The Company's subsidiaries in the PRC maintain their books and records in their local currency, the Renminbi Yuan ("RMB"), which is the functional currency as being the primary currency of the economic environment in which these entities operate. In general, for consolidation purposes, assets and liabilities of its subsidiaries whose functional currency is not the US$ are translated into US$, in accordance with ASC Topic 830-30, " Translation of Financial Statement", Translation of amounts from RMB into US$ has been made at the following exchange rates for the respective year: 2018 2017 Year-end RMB:US$1 exchange rate 6.8764 6.5064 Annual average RMB:US$1 exchange rate 6.6146 6.7570 • Retirement plan costs Contributions to retirement plans (which are defined contribution plans) are charged to general and administrative expenses in the accompanying consolidated statements of operation as the related employee service is provided. • Related parties Parties, which can be a corporation or individual, are considered to be related if the Company has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operational decisions. Companies are also considered to be related if they are subject to common control or common significant influence. • Segment reporting ASC Topic 280, " Segment Reporting • Fair value of financial instruments The carrying value of the Company's financial instruments (excluding short-term bank borrowing and convertible promissory notes): cash and cash equivalents, accounts and retention receivable, prepayments and other receivables, accounts payable, income tax payable, amount due to a related party, other payables and accrued liabilities approximate at their fair values because of the short-term nature of these financial instruments. Management believes, based on the current market prices or interest rates for similar debt instruments, the fair value of its obligation under finance lease and short-term bank borrowing approximate the carrying amount. The Company also follows the guidance of the ASC Topic 820-10, " Fair Value Measurements and Disclosures • Level 1 • Level 2: • Level 3: Fair value estimates are made at a specific point in time based on relevant market information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates. • Recent accounting pronouncements In January 2017, the Financial Accounting Standard Board ("FASB") issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) In June 2018, the FASB issued ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting In August 2018, the FASB issued Accounting Standard Update ("ASU") No. 2018-13, Fair Value Measurement (Topic 820) Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company's consolidated financial statements upon adoption.

ACCOUNTS AND RETENTION RECEIVABLE	4. ACCOUNTS AND RETENTION RECEIVABLE The majority of the Company's sales are on open credit terms and in accordance with terms specified in the contracts governing the relevant transactions.

If actual collections experience changes, revisions to the allowance may be required. Based upon the aforementioned criteria, the Company provided an allowance $12,007,545 and $0 for the years ended December 31, 2018 and 2017.

Concentrations of Risk

Concentrations of Risk	12 Months Ended

Risks and Uncertainties [Abstract]
CONCENTRATIONS OF RISK	16. CONCENTRATIONS OF RISK The Company is exposed to the following concentrations of risk: (a) Major customers For the year ended December 31, 2018, there was one customer who represented more than 10% of the Company's revenues. This customer accounted for 11% of the Company's revenues amounting to $623,187 with $695,374 of accounts receivable. For the year ended December 31, 2017, one customer represented more than 10% of the Company's revenues. This customer accounted for 48% of the Company's revenues amounting to $3,807,773 with $8,523,860 of accounts receivable. All customers are located in the PRC. (b) Major vendors For the year ended December 31, 2018, the vendors who accounted for 10% or more of the Company's purchases and its outstanding accounts payable balances as at year-end dates, are presented as follows: Year ended December 31, 2018 December 31, Vendor Purchases Percentage of Accounts Vendor A $ 1,006,974 27% $ 746,813 Vendor B 418,753 11% 3,450 Total: $ 1,425,727 38% 750,263 For the year ended December 31, 2017, there were no vendors who accounted for 10% or more of the Company's purchases. (c) Credit risk Financial instruments that are potentially subject to credit risk consist principally of trade receivables. The Company believes the concentration of credit risk in its trade receivables is substantially mitigated by its ongoing credit evaluation process and relatively short collection terms. The Company does not generally require collateral from customers. The Company evaluates the need for an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, historical trends and other information. (d) Interest rate risk As the Company has no significant interest-bearing assets, the Company's income and operating cash flows are substantially independent of changes in market interest rates. The Company's interest-rate risk arises from short-term bank borrowings. The Company manages interest rate risk by varying the issuance and maturity dates variable rate debt, limiting the amount of variable rate debt, and continually monitoring the effects of market changes in interest rates. As of December 31, 2018 and 2017, short-term bank borrowings were at fixed rates. (e) Exchange rate risk The reporting currency of the Company is US$, to date the majority of the revenues and costs are denominated in RMB and a significant portion of the assets and liabilities are denominated in RMB. As a result, the Company is exposed to foreign exchange risk as its revenues and results of operations may be affected by fluctuations in the exchange rate between US$ and RMB. If RMB depreciates against US$, the value of RMB revenues and assets as expressed in US$ financial statements will decline. The Company does not hold any derivative or other financial instruments that expose to substantial market risk. (f) Economic and political risks The Company's operations are conducted in the PRC. Accordingly, the Company's business, financial condition and results of operations may be influenced by the political, economic and legal environment in the PRC, and by the general state of the PRC economy. The Company's operations in the PRC are subject to special considerations. These include risks associated with, among others, the political, economic and legal environment and foreign currency exchange. The Company's results may be adversely affected by changes in the political and social conditions in the PRC, and by changes in governmental policies with respect to laws and regulations, anti-inflationary measures, currency conversion, remittances abroad, and rates and methods of taxation.
