Although there are many legends about Chang 'e and WU GANG, they have nothing in common, so their relationship is just to bear their own mistakes and live together in the Moon Palace.
Legend has it that WU GANG was a woodcutter who cut down trees, which angered Emperor Yan. In order to punish him, the sun god locked Wu Gang on the moon and ordered him to cut down the immortal tree, namely the laurel tree. Laurel is more than 500 meters high. Just cut it, and it'll be ready soon. Emperor Yan used this endless labor to punish WU GANG.
Chang 'e, the daughter of three emperors and five emperors, was more beautiful than ordinary people, and later married Hou Yi. Legend has it that Chang 'e ate the elixir that Hou Yi begged the Queen Mother of the West and couldn't help flying. She became a fairy in the Guanghan Palace on the moon, but Chang 'e always missed Hou Yi. The Guanghan Palace was deserted and Chang 'e lived a lonely life.
The legend of Guanghan Palace
Legend has it that WU GANG in the worse heaven is close to Chang 'e in the moon, but she often hangs to greet Chang 'e and neglects her duties. When the Jade Emperor knew about it, he was very angry. He sent WU GANG to cut down a big tree called Moon Tree on the moon. If WU GANG doesn't cut down all the moon trees, he can't go back to the worse gate and see Chang 'e.
WU GANG cut and cut for half a year from winter to summer. When the tree was about to be cut down, the Jade Emperor sent a crow to the moon tree, and with a swish, he took WU GANG's coat hanging on the tree. WU GANG immediately put down his axe and went after the crow. After the clothes were taken back, WU GANG returned to the tree and saw that all the branches and leaves that had been cut were born on the tree again.
From then on, whenever Wu Gang tried to cut down a big tree, the crow stood on the tree and shouted. As long as WU GANG stops his axe and looks at it, the big tree will grow branches again. In this way, year after year, WU GANG cut down more trees than this moon tree. Only on August 16 every year will a leaf fall from the moon to the ground. Anyone who finds the leaves of this moon tree will get inexhaustible gold and silver jewelry.
