| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| ORGANIZATION AND DESCRIPTION OF BUSINESS | NOTE 1 – ORGANIZATION AND DESCRIPTION OF BUSINESS UNION BRIDGE HOLDINGS LIMITED (formerly Costo Inc.) (the "Company") was incorporated under the laws of the State of Nevada on May 6, 2014. The Company is developing a distribution of autoparts and components necessary for maintenance and repairs of automobiles and special equipment (construction, road machinery etc.) from China to Europe and CIS countries (Kyrgyzstan, Kazakhstan, Armenia, Azerbaijan, Tajikistan, Uzbekistan). The Company has developed a growth plan that includes expansion into businesses in the health-related industry with the goal to maintaining long term sustainable growth and shareholders' wealth creation. On May 23, 2016, the Company changed its fiscal year end from November 30 to December 31. Since the Company elected to not file a Transition Report on Form 10-Q for the one-month transition period from December 1, 2015 to December 31, 2015 (the "Transition Period"), the Company has included its unaudited financial statements for the Transition Period in this report on Form 10-Q. References to fiscal years of the Company prior to fiscal 2016 refer to the fiscal years ended on November 30 in those years unless otherwise indicated. The Company now operates on a fiscal year ending on December 31, 2016. Recent Developments On February 18, 2016, Yuhua Xu, the controlling shareholder, Chief Executive Officer and sole director of the Company, entered into and closed on a Share Purchase Agreement with Mary Ho, Rudolf Novotny, Shan Ho, Lily Ho and Moana Ho (each a "Purchaser" and collectively, the "Purchasers") whereby the Purchasers purchased a total of 7,990,000 shares of the Company's common stock (the "Shares") from Yuhua Xu, for an aggregate price of $223,720. The Shares acquired represent approximately 74.53% of the issued and outstanding shares of common stock of the Company. Concurrently with the closing of the Share Purchase Agreement, Yuhua Xu, resigned as an officer and director of the Company and Moana Ho was appointed President and Chairman of the Board of Directors and Hui Zhou was appointed as a Chief Financial Officer and Director. The Company filed Amended and Restated Articles of Incorporation with the Nevada Secretary of State on May 23, 2016 to: (1) Change the Company's corporate name from COSTO INC. to UNION BRIDGE HOLDINGS LIMITED; (2) Increase the number of authorized shares of common stock, $0.001 par value, from 75,000,000 to 1,000,000,000; (3) Create a class of preferred stock consisting of 20,000,000 shares, the designations and attributes of which are left for future determination by our board of directors; and (4) Effect a 1 for 5 forward stock split of the Company's issued and outstanding common stock (the "Forward Stock Split"). Effective June 21, 2016, The Financial Information Regulatory Association, Inc. ("FINRA") approved the Company's name change and forward stock split application. All references to share and per share data have not been adjusted to give effect of the Forward Stock Split discussed above. |

| Accounting Policies [Abstract] | |
| SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS | NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS Basis of Presentation The accompanying unaudited financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments consisting of normal recurring entries necessary for a fair statement of the periods presented for: (a) the financial position; (b) the result of operations; and (c) cash flows, have been made in order to make the financial statements presented not misleading. The results of operations for such interim periods are not necessarily indicative of operations for a full year. The accompanying unaudited financial statements should be read in conjunction with the financial statements and related notes included in the Company's Annual Report on Form 10-K, for the year ended November 30, 2015, as filed with the SEC on January 21, 2016. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amount of revenues and expenses during the reporting period. Actual results could differ from these estimates. Recent accounting pronouncements Management has considered all recent accounting pronouncements issued. The Company's management believes that these recent pronouncements will not have a material effect on the Company's financial statements. |
