Why didn't Southern Buddhism rise in China?

A little look at the contents of the early translations reveals that when Buddhism was introduced into China, it was introduced regardless of its size and reproduction, but when Buddhism was introduced, Confucianism had become the mainstream of China people's thoughts.

Confucianism emphasizes that poverty is immune, and success is immune. He also said: I want to stand up and stand up, I want to touch people. This corresponds to Mahayana Buddhism's emphasis on self-interest and altruism, so Mahayana Buddhism can take root in China. If we compare it carefully, the areas where Mahayana Buddhism prevails in East Asia are also areas influenced by Confucianism, such as Japan, South Korea and Vietnam.

If your question is to compare or emphasize the irrationality of Mahayana Buddhism, it is all wet. You can only say that Southern Buddhism's emphasis on self-liberation is inconsistent with the original ideas in this area, so it has not been further developed.
