Form 3 regulatory

"COO and director Yu Baiming filed an initial ownership report"

Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.

Class B Ordinary Share financial

"beneficial ownership of 100,625 Class B Ordinary Shares"

A Class B ordinary share is a type of common stock that carries a specific set of rights—often different voting power or dividend priority—distinct from other share classes of the same company. Think of it like owning a different model of the same car: it gets you the ride (ownership and profit share) but may limit your say in steering (voting) or how quickly you receive payouts; investors care because these differences affect control, influence over management decisions, and potential return or liquidity.
