For the six months ended June 30, 2021 and 2022, the

two-class

method is applicable because the Company has Class A and Class B ordinary shares outstanding, and both classes have contractual rights with regards to dividends and distributions upon liquidation of the Company. The effect of all outstanding share options, restricted share units and convertible notes (redeemed in April 2021) were excluded from the computation of diluted loss per share for the six months ended June 30, 2021 and 2022 as they would be anti-dilutive.
