At the very least, you should know this person's real name. If this person's real name is special, such as Li Xiang, Wang Yuan, etc. It shows that this person is a person with dreams and is likely to be a little narcissistic (relatively normal, if a person doesn't even like himself, will he still like others? )。 If this person's name is not special, it is not necessarily. It may be that the host may be a little withdrawn in reality, but he wants to make friends and make others understand. Maybe it's just a temporary indulgence of one's inner emotions; Maybe just telling the truth, these should be based on some personality of the owner.
