From 23:00 today to 1:00 the next morning, this site will be temporarily closed, and the forum will be reopened at 1:00 tomorrow morning. The registration and login of the forum account will be suspended, and the iron sending and reply will be suspended. The specific recovery time is unknown. It is conservatively estimated that it will be restored as early as 10:00 tomorrow. The technical department will try to shorten the upgrade time, sorry for the inconvenience, and please understand!
