Walnut. According to Weibo sent by Zhang Linghe's support club, Zhang Linghe's fans are called walnuts. The reason is that the walnut shell is hard and brittle, which means tough and round. Walnuts are like human brains, smart and intelligent. I hope Zhang Linghe's fans will become tough, wise, tolerant and independent thinkers. There are peach characters on walnuts, and peaches also have hearts, representing Xiao Zhang's love. I hope fans can print with Xiao Zhang and get better and better together.
