First, open the homepage of Yunnan Admissions Network. Isn't there a "work network" in the lower left corner? After entering, fill in the verification code, there is a "free registration for candidates" at the bottom, and then choose your examination type (self-study, teacher qualification certificate, etc. ) and the confirmation point when you register.
After registration, you can log in with your registered user name and password. Remember, the user type column should be the same as the exam type you chose when you registered.
