Wine brewed with grain crops belongs to meat wine, and grain is used for nourishing. Using grain crops to make wine is to seize the population and grain, which is an indirect killing and a waste of personal behavior. Therefore, the vegetarian wine in Tang Sanzang should be a kind of wine brewed with fresh fruit. Buddhists do avoid alcohol, which is no problem, but as can be seen from the narrative of this original work, Tang Priest and his disciples have all drunk alcohol. Although Tang Sanzang himself is more resistant to drinking, it is not completely forbidden, and vegetarian wine is still acceptable.
For many disciples, such as Wukong, Tang Sanzang was more lenient. He thinks it's okay for them to drink some white wine, as long as they don't get drunk and delay things. Moreover, as can be seen from Tang Sanzang's narration, there are also differences between meat and vegetables in Buddhism. Seeing this, everyone's doubts depend on the word "vegetarian" of vegetarian wine. Tang Sanzang drinks vegetarian wine and refuses to drink meat wine. Wine is usually made of grain, cereal or fresh fruit. He has never heard of using meat to make wine.
Moreover, Tang Sanzang also stipulated that disciples should not get drunk to prevent drunkenness, which showed that "plain wine" is real wine, and if you drink too much, you will get drunk. The distinction between "vegetarian wine" and "meat wine" belongs to the "cultivation" of Tibetan Buddhist believers-in a strict practical sense, whether it is vegetarian wine or vegetarian wine, it is disorderly to get drunk, and according to Buddhist precepts, drinking is not allowed. In order to better satisfy their own meals, they creatively invented the distinction between meat and vegetables, which made people cry.
