Is Xiao Ye's intelligent sparring expensive? Can you share your friends with me?

I enrolled my daughter in a piano class when she was three years old, but somehow, the child never played well. Later, I saw Xiao Ye's intelligent sparring on the Internet, which was not very expensive. I thought that I had spent all my money on learning the piano, and the two thousand yuan was not bad, so I gave my daughter a membership. It's almost two years now, and the effect is quite good. My daughter plays the piano better and better. Want to know more, you can Baidu.
