Post a boring post

Some are bored, some want to ask, and some are speechless to themselves. . . By the way, I have never successfully logged in to Qitan. Except when I successfully logged in when applying for an account, I used the bookmark link to log in at other times. I was really afraid that it would suddenly expire. . . I don't know how to solve this change. If I remember correctly, the password I filled in when applying was simple. Why was the screen name and ID for the account wrong?
