Pay attention to signing your real name. When a natural person signs, he should sign his real name, that is, the current legal name on the identity document, and sign his full name. The law does not prohibit the use of abbreviations when signing.

When filling in the user name application, the user name is 6-30 letters or numbers, and the password at the beginning of the letter, such as A 123456, must and can only contain two or more letters, numbers and underscores. Such as AA 13572468.
