The tradition of the vegetarian culture of Chinese Buddhism is related to the abstention of wine and meat by the Liang Emperor Wu. The most important document in the abstention of wine and meat by the Liang Emperor Wu presented five principle in two meetings held in May 517. 1448 monks attended the first meeting. Emperor Wu declared vegetarian principle in person to the Buddhists and demanded all of them to obey. One who disobeyed would be punished and resumed secular life according to the law of Mahaparinirvanasutra （大般涅槃經） . Besides, his colleagues would be punished too if they did not report. But, some monks were not convinced. They believed that vegetarism was not in accordance with Buddhist principle. Therefore, Emperor Wu held the second meeting, in which he discussed vegetarism and Buddhist principle with several consultants. In the meeting, Emperon Wu discussed with them and declared that vegetarism was in accordance with the spirit of Buddhist mercy and statements in the Sutras of formation of the Tathagatagarbha theory. But in lack of principle guides, vegetarism was hard to be accepted by Buddhist. Therefore, the five principle which was compelling turned into , “ All monks should think about it ” （凡出家人，實宜深思）, “ Bodhisattva keep the mindful Precepts, therefore, they should not eat the meat of living creatures ”（菩薩人持心戒，故自無有食眾生理） , to advise the concept of abstention of wine and meat. Due to the lack of principle guides, Buddhist did not accept vegetarism. By May in 519, about one year later, Liang Emperor Wu finished one of his transcripts “ Receiving the Bodhisattva Precepts of Monks ” (出家人受菩薩戒法). The Brahmajalasutra* （梵網經）was introduced for the first time, and which contained abstention of wine and meat of Bodhisattva Precepts, by which vegetarism had become formally buddhism principle. In the same time, he also received the Bodhisattva Precepts and convinced people to follow it. As the Bodhisattva Precepts of “ Brahmajalasutra* ” （梵網經） was getting popular, vegetarism had turned to be the characteristic of Chinese Buddhism.
