Too many. I often meet their marketing staff. There are several in Du Rui International Center, but I only know that there seems to be one in 1 1 building. They do a good job in marketing, but I don't have children. I have no idea how it works. You can go and have a look. Generally, there are free audition classes. My name is Betsy. You'd better take the children to see if you are making a decision. It's no use talking here.
