50% are Zen Bhuddast.
12% Taosim.

Chinese are mainly Bhuddast, however it is different kind from Tibet and Tailand becuase Chinese Bhuddasim has conficous philosophy. It is like Protesten has American philosophy. You see the difference. Catholic are very strick and less free than Protesten. As for Zen Bhuddasim, it is very free as well. Which is why Chinese seems that they are less religous. But actually we are.
2. There are Taosism. Taosism is based on Laosim while Zen Bhuddasim is based on Confusisn. Lao and Confuse are two completely different philosophiers.
3. There are also Christians mainly in largest cities like ShangHai, and some Northern Chinese cities which have influences from Russia.
4. Many Muslims in China too. The Hui Chinese are Han Chinese like me except with Muslim faith. The Uygurs are Muslims too but a different race from Han.
You know that India got many many religous too. You are Hindu but there are lots of Muslims, some BHuddasts and Skih as well.
