Xiao Feiyu is quite professional. Yu, the headmaster of Fish, is a teacher from Colorful Deer in Beijing. I take my children to Beijing for an exam. My friends in Beijing recommended me to go back to Shenyang to find a teacher. After the intervention of Xiao Feiyu for almost 1 year, my child has made great progress. What I like most about Xiao Feiyu is that most of the children here are in a good mood and there is nothing wrong with their behavior.
