Essence is the treasure of cultivation, and Chinese medicine treats diseases according to this concept. Taoism and Chinese medicine believe that people get sick because of qi resistance or evil invasion of yin and yang, so they get sick. What does this have to do with taboos? Of course, Chinese medicine uses herbs to treat diseases and get angry. Therefore, after some diseases are cured, you should abstain from eating certain things for life. What about Taoism? Taoist practice is based on qi, which must be pure and pure. Especially when learning spells, the most taboo is foul gas. So what is offensive to monasticism, then what should be avoided. For example, heaven and earth are filthy, pigeon meat, beef and dog meat. Some of these meats are right, because some animals have certain virtues. We admire its spirit, so we don't eat its meat. Besides, we avoid carp, geese and mullet. There are also various irritating plants that can also affect qi, such as garlic, onions and peppers. Taoist rules are not unreasonable, but have a long history. Some things we only know but don't know why, so they are puzzling rules to outsiders.
