According to the six paths of reincarnation in Buddhism, Heiyu's previous life was probably a combative being like Rakshasa ghosts and gods in the heaven. After all his blessings were exhausted, he fell to the lower world and became a fish. Therefore, Heiyu has always been known for its ferocity. , is the overlord of the water. In "Journey to the West", there is a story about Guanyin Bodhisattva subduing the black fish spirit. Therefore, everyone must not kill black fish in the future to avoid suffering retribution in reincarnation. Of course, other living beings cannot be killed either. Another note: The energy of the Seven Stars of the Big Dipper is very powerful. Zhuge Liang's original seven-star lantern array at Wuzhang was not successful in extending his life, mainly because Zhuge Liang had too much murderous karma and his end was approaching. Thich Nhat Hanh, a famous monk in the Tang Dynasty, also passed down the Big Dipper Dharma, which can protect all living beings from the evil stars in the passing years (I have obtained this Dharma and kept it secret).
