Futu Niu Niu cannot open an account.

If Futu Niu Niu cannot open an account, it may be one of the following reasons: 1. Incorrect information input: Make sure the information such as ID card, bank card and telephone number is accurate. 2. The account has been registered: If the Futu Niu Niu account is registered, you need to log in with the existing account or contact customer service to solve the problem. 3. A single user opens multiple accounts in a short time: If you try to open multiple accounts in a short time, you may be identified as a duplicate account and rejected by the system. 4. Unstable network: Please make sure the network connection is stable, and then try to open an account again. If the above methods can't solve the problem, I suggest you contact Futu Niu Niu Customer Service for detailed consultation and help, so as to find a suitable solution.
