According to the concept of Buddhism, you should not kill animals to eat meat, but all living beings usually can't do it.

There is another more important reason why the ancients advocated vegetarianism. Heaven has the virtue of loving and killing. Heaven and earth breed all things, and they like life and hate death. Look into the heart of heaven and earth and take killing as a warning. The best way is to advocate vegetarianism.

With the introduction of Buddhism, Liang Wudi, known as the "Bodhisattva Emperor" in the Northern and Southern Dynasties, made vegetarianism a prominent feature of Mahayana Buddhism in China.
