My friend's child learned it in a music classroom in the East Coast Holiday Community of Yingbin Road. I think it's called Bessie Music Classroom. The teacher graduated from a professional conservatory of music and has a set of methods to teach new children. Children are very receptive, efficient and willing to learn, and the price is very cheap. If you are interested, you may wish to consult. The telephone number is 0898-88697322.
