Why did the sign of frozen fish turn red?

It has gone bad. Jiang Xiaoyu is a Chinese zombie produced by Xiamen Yufeng Animation Co., Ltd. It has a fishbone on its head, wearing an official uniform, black eyes and a lovely face. Frozen fish and frozen symbols are different souls that exist in one body. Fish has a gentle personality, and the yellow symbol indicates that it is a stiff fish in the body at this time. Once the symbol turns red, it is dominated by a small symbol with a stiff heart. At this time, the stiff little symbol will make the opposite character and behavior to the stiff little fish.
