I can't get the verification of the four-level application email

1. Check the spam box: sometimes the verification email will be misjudged as spam. You can check whether there are related messages in the spam box.

2. Check whether the email address is correct: Please make sure that the email address you entered is correct. If any letters or symbols are entered incorrectly, you will not receive an email.

3. Change email address: If you still can't receive the verification email after trying the above two methods, you can try to change an email address and verify again.

4. Contact relevant departments: If all the above methods fail, you can contact relevant departments at Level 4 for help and solutions.
