How to cancel Lucheng 365 after registration?

I want to ask how to cancel the registration of Lucheng Health 365. Once the account of Lucheng Health 365 is registered, it cannot be cancelled by itself.

If you need to give up your original account, you can cancel and re-register.

In the personal center of the official account of "Lucheng Health 365" WeChat, click Exit to cancel the account, then click Please Login in the lower left corner, select Register and enter a new mobile phone number.
