Because Jesus is a foreign thing, with the support of foreign churches, too many restrictions will lead to external political pressure, so the government can't restrict too much. For example, foreign churches donate a lot of money to support religious activities in China, but the government does not allow churches to accept foreign funds, so they donate paper to print bibles. Therefore, China's Bible is the cheapest in the world, and many people from Hong Kong and Taiwan buy it from the mainland and take it back.

Foreigners who believe in religion in the local area pay little attention to it and will naturally be subject to more restrictions. For example, monks traveling in clouds have to buy tickets to places like Yungang and Longmen Grottoes. Such Buddhist heritage is completely occupied by the government, and temples with monks are also dominated by the government.
