First, Taoism respects life very much, so it can actually be a sect with Confucianism in history, so they also respect life very much. They pay attention not to harm life, such as not eating cows or dogs. All these lives are beneficial to human beings. The reason why Taoism doesn't eat cows is because the mount of Taoist Laozi is a green cow, and dogs are also because dogs are the most humane animals. In ancient times, dogs were a kind of friend of human beings.
Second, Taoist priests don't eat mullet. Poor mullet is the most pitiful, because mullet mother will be blind for a period of time when she gives birth to small mullet. If the baby mullet swims before it is born, it will soon be eaten by the mother mullet who can't see. In fact, mullet is very rare.
3. Taoists don't eat wild geese. They don't eat wild geese because they are in awe of the love between wild geese. They have dreams and fantasies about beautiful love, so Taoism is very moved by the feelings of accompanying geese. They think that killing a wild goose will make another wild goose very lonely, so Taoism will never allow it to be a wild goose.
Taoism attaches great importance to people's emotions, which is why they don't eat these four kinds, which have continued until now. Taoism has always been a people-centered Sect. Although Taoism did not flourish in ancient times, many of Laozi's sayings are now used by later generations. In modern times, Taoism is still highly respected.
