General and administrative fees The following table sets forth a summary of our general and administrative expenses for the years ended December 31, 2023, and 2022. The decrease in general and administrative fees was primary due to the reversal of deferred cash bonus payables to employees and reduction of employees during current period. The reversal was due to the Group’s agreements with employees to discharge the Group’s obligation to settle their outstanding deferred cash bonus payables from previous years in exchange of fully vested ordinary shares.
