The word “worship” is very misleading here because it has religious connotations.
The Chinese don’t “worship” their ancestors; they have ceremonies where they pay respect to them. They do not elevate their ancestors to god status, but they recognize that each generation builds on what their ancestors have left them.
In the same vein, they did not have anything near to the western or Jewish concept of heaven. It was just a vague concept of a place souls went to after they died.
