At present, the better ones are: deep blue education, Fudan Qiushi. The teachers there are all specialized in technical fields, and Deep Blue seems to have 1 to 1 to teach alone. Off-topic, if you want to achieve financial freedom by the stock market, I have the following serious suggestions: first of all, you need to have a stable job and you don't need to rely on the stock market to support yourself at all. Similarly, the loss of the stock market will not affect your life. Second, if you have a teacher who can keep a steady income for more than five years, don't read books. The master's advice is more useful than reading twenty or thirty speculative books. I only recommend reading The Road to Financial Freedom and Psychoanalysis of Trading under the guidance of experienced people.
