Berries make effort to introduce concept through play and touch. For example, when they teach 花开了， each child gets a handicraft that demonstrate the flower opened. Another example, when they introduce the word 啄木鸟 （woodpecker), each child gets a toy like the one in the picture.
I think all of us heard abour Berries （百力果）and Tian Hsia (天下). Their popularity owe to their numerous outlets and, of course, their proven track records. One of my colleges actually sent her son to both! Her feedback is Berries is more structured. I personally like Berries because they are stronger with preschoolers while Tien Hsia is better as a tuition.
Without doubt, any parent will agree that whatever is taught using this play to reinforce learning, will be remembered.
So even if Berries charges are a notch higher, i think it is worth every cents as it stimulate long term interest. My child looks forward to attending each lesson.
In addition to Berries, my child continue using 熊猫乐园 to play and learn. He also learn Hanyupinying （汉语拼音）and Maths through this software.
