According to legend, in ancient times, there were ten days in the sky at the same time, the crops died in the sun and the people were poor. A hero named Hou Yi has infinite power. He sympathized with the suffering people, climbed to the top of Kunlun Mountain, made full use of his divine power, drew his bow, shot down more than nine suns in one breath, and ordered the last one to rise and fall on time for the benefit of the people.

Hou Yi was respected and loved by the people. He married a beautiful and kind wife named Chang 'e. Besides hunting, Hou Yi spends all his time with his wife, and people envy this beautiful and loving couple.

Many people with lofty ideals came here to study as teachers, and Meng Peng with ulterior motives joined in.

One day, Hou Yi went to Kunlun Mountain to visit friends and seek truth. He happened to meet the Queen Mother passing by and asked her for a bag of elixir. It is said that taking this medicine can immediately ascend to heaven. However, Hou Yi was reluctant to leave his wife, so he had to temporarily give the elixir to Chang 'e. Chang 'e hid the medicine in the dresser's treasure chest, but the villain Meng Peng saw it. He wants to steal the elixir to make himself immortal.

Three days later, Hou Yi led his entourage out hunting, while Meng Peng with ulterior motives pretended to be ill. Shortly after Hou Yi led the crowd to leave, Meng Peng broke into the backyard of the back room with a sword in his hand, threatening Chang 'e to hand over the elixir. Chang 'e knew that she was no match for Meng Peng. In times of crisis, she made a decisive decision, turned around and opened the treasure chest, took out the elixir and swallowed it in one gulp. Chang 'e swallowed the medicine and immediately floated off the ground, rushed out of the window and flew into the sky. Because Chang 'e was worried about her husband, she flew to the nearest moon and became a fairy.

In the evening, when Hou Yi came home, the maids cried and told what happened during the day. Hou Yi was surprised and angry, and drew his sword to kill the villain. Meng Peng escaped early. Angry and heartbroken, Hou Yi looked up at the night sky and shouted the name of his beloved wife. At this time, he was surprised to find that today's moon is exceptionally bright and bright. There is a swaying figure resembling Chang 'e. He chased the moon desperately, but he chased it three times, the moon retreated three times, he retreated three times, and the moon advanced three times. He couldn't catch up anyway.

Hou Yi had no choice but to miss his wife, so he had to send someone to Chang 'e's favorite back garden, put on a table sweetmeats, put on her favorite honey and fresh fruit, and offer a remote sacrifice to Chang 'e who was attached to him in the moon palace. After hearing the news that the Goddess Chang'e flying to the moon became an immortal, people made an incense table under the moon and prayed for good luck and peace to the kind Chang 'e.

Since then, the custom of Mid-Autumn Festival in Yue Bai has spread among the people.
