Some people’s personalities can indeed be reflected through their WeChat avatars, but it cannot be said that this is the case for all people, because there are many people like me who randomly create avatars and end up too lazy to change them.

Common couple avatars can reflect their personalities. The current status is that they have a partner and are showing off their affection. If the avatar is cute, then the girl should have a cute personality, and the boy will be very fond of doting on the girl. If it's more non-mainstream, it should be that both parties have weird personalities.

If you are a mother who likes to use landscapes and flowers as avatars, then your personality is probably more cheerful. If your avatar is serious, your personality should be more rigorous.

If a boy likes to use non-mainstream handsome guys as his avatar, then his personality should be more like a young and Dangerous boy, which is a bit carefree. He pays great attention to the loyalty between brothers and longs for a vigorous love.

If you're like me, your avatar can't reflect your personality, it can only reflect what I used to like. My QQ avatar is a character from the anime "Hunter" that I particularly liked back then, Killua: Killua. My Weibo avatar is two people from a boy band that I like very much. My WeChat avatar is an emoticon of a professional lol player, but I’m not actually a fan of his because I have other players I like more, but I just like his emoticon so I use it. Then I was too lazy to change. I have been using QQ avatar for almost 10 years and have never changed it during this period.

So, the avatar can indeed reflect what a person likes at that time to a certain extent, and even his personality, but not everyone can reflect it through the avatar. After all, the human heart is elusive.
