Tell him: what's the panic? Most domestic investors are deeply involved, and some institutions and bookmakers are also deeply involved. As for the stocks bought by various funds under the fund company with the money of the general public, they are all locked up. There is an old saying that failure is fear, and failure is the mother of success. Now you finally become a mother because of failure. It is only a matter of time before a successful son is born. It won't be long before you carefully choose your son (stock).
