How does China Railway koi fish cancel its account?

Hello, I'm glad to help you solve the problem. I have met them before. The following is my personal opinion. I hope I can help you. Please forgive me if there is any mistake! If the manager wants to cancel his registration temporarily after seeing it, you can cancel it, or you can continue to use it without canceling it. Thank you very much for your patience. Please adopt it if it helps. Wish you a happy life! thank you
