You can't open an account in a securities company, but you can open an account in a futures company or contact some brokers of other companies online, such as me, to give you a courier contract. After filling out the email, my futures company will open an account for you.
Nanjing Securities can't. If it is not handled properly, it will lose money. This kind of situation is relatively rare, and it is usually when there is a daily limit. We can communicate more.
