Fortune-telling is forbidden in the Koran.

What will happen if Han people continue to eat big meat and burn incense and worship Buddha after entering Islam?

Nothing will happen. It's just that we are forbidden to eat meat. Because it is dirty. Calculate divination, burn incense and worship Buddha. These idolatrous behaviors. This is forbidden by God. Unforgettable Because Islam is a monotheistic religion, why do you believe in God and burn incense and worship Buddha? Allah said, even if you come to see me with the sins of the whole earth, I will forgive you with the tolerance of the whole earth, except those who worship other idols.
