I know this problem. I live near Wudaokou. My children also have some interest classes, and often go to Haidian or Chaoyang for classes. I know one in Haidian and nine in the forest, one-on-one tutoring. It can also point out the similarities and differences of children, and the teaching quality is excellent. If you live not far away, go and have a look! For the sake of children, I hope to adopt!
