Bond bar, with many branches, mainly supplements mathematics, science and English. Bond is good at math, not bad at science, and not so good at English. If your children get good grades, you can go to an advanced class. If you want to practice oral English, you can go to EF Midland and other institutions for training. It doesn't take long to learn spoken English. For example, I only practiced for one year to cope with the senior high school entrance examination. Of course, if your child wants to develop in English, you can train for a long time.

To tell the truth, it's ok to find a training institution in summer and winter vacation, but it's best to find a familiar and qualified teacher to make up lessons, especially at school, because the teacher will know more about your study, and the students will be very serious in front of the familiar teacher, and the tuition fee is similar, but in the training institution, your child's seriousness can't be guaranteed. Of course, if your child is serious, it is no problem to go to a training institution.

It seems that there are institutions like Blue Sky and Feiyue Island in Shenzhen.

I hope my answer is helpful to you.
