     RE:  YINGLI GREEN ENERGY HOLDING COMPANY LIMITED
          REGISTRATION STATEMENT ON FORM F-1 (FILE NO. 333-147223)

Dear Ms. Fisher and Mr. Mumford:

     On behalf of our client, Yingli Green Energy Holding Company Limited, an
exempted company organized under the laws of the Cayman Islands (the "Company"),
we are enclosing four (4) courtesy copies of Amendment No. 1 ("Amendment No. 1")
to the Company's registration statement on Form F-1, which has been filed today
on EDGAR with the Securities and Exchange Commission (the "Commission"). For
your ease of reference, the enclosed hard copies of Amendment No. 1 are marked
to show changes to the Company's registration statement filed with the
Commission on November 7, 2007 (the "Registration Statement"). On behalf of the
Company, we wish to thank you and the other members of the Commission (the
"Staff") for your prompt comments on the Registration Statement.

                                        2

     The Company has responded to all of the Staff's comments either by revising
the Registration Statement to comply with the Staff's comments, providing an
explanation if the Company has not so revised or providing supplemental
information as requested. In addition to the revisions made in response to the
Staff's comments, the Company has revised the Registration Statement to (i)
include the information relating to the proposed concurrent offering of
US$150,000,000 Zero Coupon Convertible Senior Notes of the Company; (ii) remove
the information relating to the proposed offering by the Company of 3,000,000
ADSs; (iii) include further information on the selling shareholders; and (iv)
otherwise enhance disclosure generally.

     Subject to market conditions, the Company currently plans to bulk-print its
preliminary prospectus and to commence the road show for this concurrent
offering of the ADSs and convertible notes on or about November 26, 2007 and
expects to price this offering on or about November 29, 2007. The Company would
very much appreciate the assistance of the Staff in working towards this goal.

     Set forth below are the Company's responses to the comments contained in
the letter dated November 20, 2007 from the Staff. The comments are retyped
below for your ease of reference and are followed by our responses thereto. In
our responses, we have included page numbers to refer to the location of
