There is no such thing as "vegetarianism" in Buddhism. Eating vegetarianism is a combination of Chinese culture after Buddhism was introduced to China, and a Buddhist came out to "eat vegetarianism".

Nowadays, most of our monks complete their daily practice in the temple, but even when they were old, they were always begging for alms among the people, just to enter the country without being contaminated by dust.
Begging for alms is what the people say, just take a bowl and ask someone to beg for food, and eat whatever they give. When you meet a wealthy family, you may have fish and meat. When you meet a poor person, you may have a little less. However, you must not make any requests or refuse. Therefore, Buddhists can originally eat meat.

There is a saying that "eating vegetarian food" was introduced to China. It began with the promotion of (502-549) in the Southern and Northern Dynasties. Emperor Wu of Liang read the "Lankavatara Sutra", which says, "The Bodhisattva is merciful and merciful, and cannot bear to eat the meat of sentient beings." After reading it, he was very moved and made a vow to eat vegetarian food for a long time. Buddhism formed the characteristics of Chinese Buddhist on the grounds that the emperor praised "vegetarianism", and quickly influenced the entire monastic community.

Nowadays, although Buddhism is prevalent in other Buddhist countries and regions, no one has promoted the vegetarian movement. He still maintains the teachings of the Buddha in his early years. He begs for alms and can eat three pure meat or five pure meat , because the most basic skill that Buddhists talk about is that they cannot be attached to appearances, that is, meat is not meat, bad people are not bad people.
