If we haven't really touched a person, no matter how we evaluate him, it may be incorrect. Because people are multifaceted, they will have different personalities in different situations. If we want to know a person, it is best to get to know each other's character through more contact and communication with each other and through some small things in life. It is impossible to accurately judge a person's personality in a short time.
However, to some extent, we can see a person's character by using WeChat facial words. Because there are really many styles of expression packs now, only those who are interested in that style will download that type of expression pack, and only those who are moved by that expression pack will want to collect it. Therefore, from this perspective, it is not unreasonable to see a person's personality through WeChat.
However, as mentioned above, this is probably just a part of his personality. If you want to really understand or fully understand a person, you still have to communicate with each other in your life. Moreover, it is also possible that this is just a display made by the other party on purpose.
In any case, the expression pack of the other person can indeed be used by us to roughly judge the other person's personality, but we can't rely too much on this way. At best, it is a combination judgment of many ways. Try to associate with others, no matter what his personality, you can be friends.
