How to understand that ancient religion in China is an important part of ancient culture in China?

Religious culture permeates every corner of social life.

For example, we don't burn incense at ordinary times, but cram for the Buddha's feet. Everyone knows this sentence, which is a response to the popularization of Buddhist culture.

See the big from the small. This proves that China's ancient religion has a great influence on China, and China's ancient religion is an important part of China's ancient culture.

But it should be noted that we should not only see Buddhism and Taoism, but also see patriarchal religions-patriarchal traditional religions, Maitreya/Zoroastrianism, and other small religions.

As for Buddhism, China has not only Mahayana, but also Hinayana, which is already taught by lamas.
