Zhicheng

I would strongly advise against using Zhicheng. They even stole my money without any notice. They charged me three years of interest without informing me. Avoid them at all costs.

I've been with them for 7 years, and while their order execution is decent, it's nothing extraordinary. Spreads are low, but not the lowest in the market. Payment processing is indeed fast, and they do offer various deposit methods. Customer support is responsive, but the account managers' assistance varies. Some are helpful, while others seem disinterested.
