       General

   1.                                                   We note the changes you
made to your disclosure appearing on the Cover Page, Summary
                                                        and Risk Factor
sections relating to legal and operational risks associated with operating
                                                        in China and PRC
regulations. It is unclear to us that there have been changes in the
                                                        regulatory environment
in the PRC since the prior amendment that was filed on January 9,
                                                        2024, warranting
revised disclosure to mitigate the challenges you face and related
                                                        disclosures. The Sample
Letters to China-Based Companies sought specific disclosure
                                                        relating to the risk
that the PRC government may intervene in or influence your operations
                                                        at any time, or may
exert control over operations of your business, which could result in a
                                                        material change in your
operations and/or the value of the securities you are registering
                                                        for sale. We remind you

                                                        defined in Securities
