What does the ancient red moon symbolize?

When the total lunar eclipse occurs, the sunlight in the area where the moon is located can't be direct at all. But through the earth's atmosphere, there will still be a little sunlight refracted into the earth's shadow. Therefore, from the earth's point of view, the moon did not disappear from the sky, but showed a rare bronze color, which is commonly known as the "red moon."

In ancient times, there was a legend that tengu ate the moon. It is said that there was a son named "Mulian" in ancient times. Born a good Buddha, a kind person. She is very filial to her mother, but Mulian's mother, as a queen, is irritable and likes and dislikes. On one occasion, Manglietia's mother suddenly had a whim and came up with a bad idea: monks read Buddha and become vegetarians. I want to play tricks on them and eat dog meat. She ordered to make 360 dog meat buns, saying they were vegetarian buns, and they were going to the temple to give them. Mulian knew about it, advised his mother not to listen, and sent someone to inform the abbot of the temple. The abbot prepared 360 vegetarian steamed buns. Hidden in every monk's cassock sleeve. Mulian's mother came to give alms and gave each monk a dog meat steamed bread. Before the meal, the monk recited the Buddha and replaced the dog meat steamed bread in his sleeve with vegetarian steamed bread before eating. Seeing that all the monks had eaten her steamed bread, Mu Lian clapped her hands and said with a smile, "Today all the monks are dizzy! Monks eat dog meat steamed buns! " The abbot folded his hands and repeated, "Amitabha, sin, sin!" " "Afterwards, 360 dog meat steamed buns were buried in the soil behind the temple. The jade emperor in the sky was very angry when he learned about it. Will lay Manglietia's mother down to eighteen levels of hell, become a vicious dog, and will never be reborn. Manglietia was a dutiful son and learned that her mother had gone to hell. He practiced day and night and finally became a Buddha. In order to save his mother, he used Zhang Xi to open the door of hell. The mother of Manglietia Manglietia and all the evil spirits escaped from hell and were reincarnated to make trouble on earth. The Jade Emperor was furious and made Manglietia descend to earth to devote herself to Huang Chao. Later, "Huang Chao killed eight million people", and the legend came to collect these evil spirits who escaped from hell. Manglietia's mother turned into a vicious dog. After escaping from hell, she hated the jade emperor and went to heaven to get even with him. She couldn't find the jade emperor in the sky, so she chased the sun and the moon, trying to swallow them and turn heaven and earth into a dark world. This evil dog chases and chases day and night! She chased the moon and swallowed it; Catch up with the sun and swallow it in one gulp. The evil dog that Mulian's mother turned into was most afraid of gongs and firecrackers, and the sun and moon swallowed by the evil dog would spit it out again. After the sun and the moon were rescued, the sun, the moon and Hui Qi started running again. Bad dogs don't want to catch up again, so there are eclipses in the sky again and again. Folks call it "Tengu eats the sun" and "Tengu eats the moon". Up to now, during solar and lunar eclipses, many people in cities and rural areas still have the custom of beating gongs and drums and setting off firecrackers to drive away Tengu.
