A "long grass dumpling" with two leaves on its head, a "little zombie" with a yellow symbol on its forehead, a "rabbit with a broken ear" with a small piece missing from its left ear, and a "frozen girl" with dark skin and often going crazy ... These soft and cute images often appear in the expression library of WeChat. Whether it's greeting good morning, sarcasm or trying to make faces at each other, you can find the right expression.
