Mainly, the Chinese don't even know they have a religion. What they believe is so old that they just regard it as being Chinese. There is no word in Chinese for religion.
But they do have a religion. Scholars like to say it is Buddhism, Taoism and Confusianism. This is a common mistake. The main religion is ancestor worhip and every home has a family religious shrine. Scholars are largely unaware of this because few see these shrines. Chinese do not invite you into their homes. They entertain you in resturants because their homes are shrines to their ancestors. Liondancing, burning paper money, Chinese opera are all ways to playcate the ancestor spirits they believe hover around periodically.
They also have some gods which they have idols they burn joss sticks for and bow to. I have seen many of these idols and some have many arms and heads. Their god panthion is always in a state of flux.
The Chinese do not know what they believe is a religion. To them it is just "being Chinese."
