Insert music in the post bar, and there will be hints when posting. Please don't post messages containing inappropriate content, and please don't post advertisements.
This is not your problem, and it is not that you can't make music. Now Baidu Post Bar is getting more and more outrageous. You must have broken the harmony with a word. I suggest you go to Baidu to find harmonizer, put the words you want to send in, and it will tell you the reason. That's all we can do at present, otherwise we can complain.
