Cause: According to legend, in ancient times, there were ten suns in the blue sky, which caused the earth to crack, crops to wither, and people to live in dire straits. There was a hero named Hou Yi, who was extremely powerful. He sympathized with the suffering people. He climbed to the top of the Kunlun Mountains, used his supernatural power, drew his magic bow, and shot down nine suns in one breath. He also strictly ordered the last sun to rise and set on time. Benefit the people. Hou Yi was respected and loved by the people.

History: Later, Hou Yi married a beautiful and kind-hearted wife named Chang'e. In addition to spreading his skills and hunting, Hou Yi stayed with his wife all day long. People envied this loving couple with talent and beauty.

Hou Yi's reputation spread far and wide, and many people with lofty ideals came to study with him. Peng Meng, who had evil intentions, also got in.

One day, Hou Yi went to Kunlun Mountain to visit friends and seek enlightenment. By chance, he met the Queen Mother who was passing by. The Queen Mother gave him an elixir of life. It is said that if you take this medicine, you can immediately ascend to heaven and become an immortal.

However, Hou Yi was reluctant to leave his wife and did not want to become an immortal alone, so he temporarily gave the elixir to Chang'e for collection. Chang'e hid the medicine in the treasure box on the dressing table. Unexpectedly, the villain Peng Meng saw it. He wanted to steal the elixir and become an immortal himself.

Three days later, Hou Yi led his disciples out for hunting. Peng Meng, who had evil intentions, pretended to be sick and stayed behind. Soon after Hou Yi led everyone away, Peng Meng broke into the backyard of the inner house with a sword and forced Chang'e to hand over the elixir.

Chang'e knew that she was no match for Peng Meng. In the critical moment, she made a prompt decision, turned around, opened the treasure box, took out the elixir and swallowed it in one gulp.

Chang'e swallowed the medicine, and her body immediately floated off the ground, rushed out of the window, and flew to the sky. Because Chang'e cared about her husband, she flew to the moon closest to the world and became an immortal.

After hearing the news that his wife had arrived on the moon, Hou Yi was heartbroken and chased after the moon desperately. However, when he advances, the moon also advances; when he retreats, the moon also retreats, and he can never catch up.

Yi missed Chang'e and could only look at the moon in trance. At this time, the moon is also extraordinarily round and bright, just like his beloved wife looking at him.

On the night of August 15th of the following year, Chang'e walked out of the Moon Palace and silently looked into the lower world, missing her husband and fellow villagers. Her beautiful face made the moon extra round and bright.

After Chang'e arrived at the Moon Palace, she missed her husband very much, and Hou Yi also thought about it day and night, hoping to see his wife again.

One day, an immortal showed Hou Yi the method: on the night of the full moon on August 15, make balls of flour into a shape like a full moon, place them in the northwest direction of the house, and then If you continue to call Chang'e's name, Chang'e can go home and be reunited at the third watch.

Houyi did as he was told, and he saw Chang'e flying from the moon, and the couple reunited. The dough balls made from this flour later evolved into various moon cakes.

Result: Hou Yi and his fellow villagers all worshiped the moon under the moonlight to express their longing for Chang'e. This has been the case every year since then, passed down from generation to generation. Since August 15th is the Mid-Autumn Festival, it is designated as the Mid-Autumn Festival.
