[1] Receivables from third party payment service providers represent cash due from the Group’s third party on-line payment service providers in relation to their processing of payments for the Group.

[2] As of March 31, 2023, the Company has purchased physical gold of RMB32,378 in total. As the Company intends to hold the gold for an indefinite long term period, the Company has recorded the asset in “other non-current assets” on the Consolidated Balance Sheets. The Company will record any decline in net realizable value lower than acquisition cost as a non-operating loss. The net realizable value is determined based on market value less cost to sale. Any recovery in valuation will only be recognized to the extent of previously recorded fiscal year losses, and only to the extent such recovery occurs in the same fiscal year as when such losses were recorded. As of March 31, 2023, the market value of the gold less cost to sell was higher than its purchase cost. Therefore, there was no impairment loss recognized for the year ended March 31, 2023.
