Sell one's income. Sister Xiaoyu is a character in the first sequence of the novel. The author of this novel is a "talking elbow". In the 20th chapter, when the male director Xiao Su was wounded and dying by wolves, it was Sister Xiaoyu who saved Xiao Su's life with the money she exchanged for drugs. The most important thing is that she did a good deed without leaving her name. If it weren't for six dollars, I found that Sister Xiaoyu's anti-inflammatory drug was exactly the same as last time, and she wouldn't have done it at all.
