I know that there are no such things as heaven, god, emperor and god, but we made them up. I agree with this, because I was educated in atheism since I was a child. This kind of education is deeply rooted, even if someone believes in Buddhism and religion, it will be regarded as superstition by me and subjectively rejected.
It still is. Let me give you a simple example. Once we organized a group to play in Wofo Mountain, and we all looked sideways like tour guides (it would be more like this). Looking at us, a colleague who never spoke suddenly said to me, "Heaven and earth are all Buddhas, and a Buddha in your heart is a Buddha."
