You mean brave (sound: Pi Xiu)? The legend of the brave without anus is like this: It is said that one day the Jade Emperor held a birthday party to entertain the Dragon King. When you know this, you must go with your father. The dragon king doted too much and had to agree. Its staple food is gold and silver jewelry, which is naturally full of treasures. Compared with other three-legged toads, which are also auspicious animals, it is much more important, so it won the favor of the Jade Emperor and the Dragon King. At the banquet, because animals and immortals eat very different things, I went to find food myself, and as a result, I ate all the gold and silver jewelry in the palace mourning hall. But I have a hobby, that is, I always have diarrhea when I urinate anywhere, so I can't help it. Since then, mythical animals have lived on earth, and gold, silver and jewels can only enter but not leave. After the story spread, mythical animals were regarded as lucky beasts.
