Key Information, page 3 2. We note your revised disclosures in response to prior comment 3.

Please explain why the amounts disclosed in your proposed revised disclosures to prior comment 5 do not agree to the amounts disclosed in the revised consolidating worksheets for "intercompany costs and expenses." 4. We note your revised presentation in response to prior comment 8. Please further revise to present a separate column for the WFOEs that are the primary beneficiaries, which appear to be Suzhou Stack Data Technology Investment Company Limited and Hebei Stack Data Technology Investment Company Limited and their respective subsidiaries. Also, tell us what the "other subsidiaries" column represents and how these subsidiaries differ from the other subsidiaries included in the WFOE column in your proposed revised disclosures. If this column relates to subsidiaries of the WFOE or the Parent, please move the placement of the column in the worksheet so that it is clear to which entity the subsidiaries belong. 5. Please revise your consolidating balance sheets data to present investments in subsidiaries separately from contractual interest in VIEs.
