Han Buddhism has a dietary custom of "fasting", and fasting is vegetarian, which is a unique system in Han Buddhism. Indian Buddhists are forbidden to eat meat, that is, five kinds of vegetables with strong smell and stimulating effect, such as onion, onion, garlic, leek and canal, which are called "five spices" or "five meats" The Law of Ten Chants stipulates that monks are strictly forbidden to eat meat, but they can eat "three clean meats" that are "unseen, unheard of and not suspected". During the spread of Buddhism to the East, monks in China adhered to this dietary custom. It was only in the Northern and Southern Dynasties that Liang Wudi, who believed in Buddhism, began to advocate vegetarianism, advocated that monks and nuns should abstain from meat, severely punished monks and nuns who did not obey the precepts and drank and ate meat, and began to rectify it from the upper monks, making vegetarianism a unique dietary system for Chinese Buddhists.
