Eggs are customarily classified as meat dishes, at least not vegetarian dishes. Western vegetarianism is also divided into egg milk vegetarians and pickled vegetarians. In some groups, not eating eggs is mainly because eggs can hatch life, and not eating eggs is to stop killing. From the perspective of traditional Chinese medicine, it means that eating too many eggs is easy to stagnate. However, with the changes of the times, there are two kinds of eggs now: one can hatch and the other can't hatch. Therefore, it has been recognized by some groups that some places or some people eat eggs that can't hatch (that is, there is no life) because of health or environmental habits. In short, the key to being a vegetarian is whether to kill or not, and the most important thing is to maintain the inner "vegetarian".
