Because all the names you have given have already been used, you are prompted to repeat them.
I'll teach you several ways:
1. Type an Enter key in any blank text, then copy the text typed by this Enter key, and then paste an Enter key in the middle of each word of the name you want to change, only three words.
2. For example, name XXX, but this name is definitely taken. At this time, the player only needs to add QQ or sogou expression after XXX, and copy an expression from the chat record and put it after XXX.
3. Choose some wonderful names.
