Haitong Securities e-Haitongcai has low commissions (1.2 million for stocks and 0.5 million for funds). I did some research on the app and found that it is generally pretty good, but there is one drawback: the automatic trading function is missing.

For example, Guotai Junan can invest in ETFs and automatically trade according to conditions.

Haitong can only intelligently track the market, and will remind you to trade manually when the conditions are met.
