       Cover Page

   1.                                                   Please disclose here
and in the prospectus summary whether your auditor is subject to the
                                                        determinations
announced by the PCAOB on December 16, 2021 and whether and how
                                                        the Holding Foreign
Companies Accountable Act and related regulations will affect your

2.       We note your response to prior comment no. 3. Please clarify whether
the stock-based
         compensation amounts included in the pro forma net loss per share were
separately
         determined for each period as if the IPO was effective as of each
reporting date. That is,
         explain whether the RMD49.9 stock-based compensation recorded for the
nine months
         ending September 30, 2021 includes expenses attributable to options
that were
         outstanding during 2020. The pro forma stock-compensation expense
should be
         calculated assuming that the IPO was effective on January 1, 2020 for
both reporting
         periods, and that the service conditions that were met through the IPO
effectiveness date
         were met as of January 1, 2020.
Risk Factors
Our auditor is currently not subject to inspections by the PCAOB..., page 29

3.       Please update your disclosure to reflect that the PCAOB has issued its
report notifying the
         Commission of its determination that it is unable to inspect or
investigate completely
         accounting firms headquartered in mainland China or Hong Kong.
