I heard Huatai Securities is going to close down?

No way, I am also in Huatai. All this information on the Internet is hearsay and unreliable. To say the least, even if Huatai really fails, it can be transferred. Even if not, the state will arrange for other securities companies to receive all customers. Besides, you haven't understood the meaning of tripartite depository. Huatai can't move your stock, so there is no such possibility technically. Don't worry about safety

In addition, the transfer is also very simple. On the first day, I will settle the interest and transfer the cash in my account. The next day, I cancelled the designated transaction in Shanghai (it doesn't matter whether there are Shanghai stocks or not) and cancelled the agency relationship in Shenzhen. If you have deep stocks, you have to pay a custody fee of 30 yuan to transfer to the securities company you want to go to, but the securities company you go to can reimburse you. In addition, it is necessary to cancel the tripartite depository with CCB. On the third day, you can transfer to a new securities company. Remember that you have to do business during these three trading days, and you can't do any trading during these three days.
