How Chinese government controls domestic religions?

This was an entrance exam paper for Nanjing Union Theological Seminary. However, in this exam paper, you saw nothing about religions, and everything was about the explanations of the Communist Party's policy. If You want to go into the theological seminary, you have to learn the Communist Party's files rather than the Bible.

This is one way how the Chinese Communist Party controls domestic religions: to tell the students to keep loyalty to the Party even they choose a non-secular way.
