The dragon is full of fire, and China's idiom comes from "Zhuangzi Health Master": "It is said that the salary is poor, and the fire also spreads. I don't know what to do." The original intention is that the previous firewood has just been burned, and the last firewood has been burned, and the fire will never go out; Although the wood is burned out, the fire still exists; It is a metaphor that Master passed on karma to his disciples from generation to generation.
