What do the six nights in the lunar calendar represent?

Liu Yao, also known as the Star of Liu Yao and the Little Six, is a note in the traditional calendar of China, which is used to mark bad luck every day. Liu Yao originated in China. Legend has it that Zhuge Liang initiated it and called it "the Six Obsidian Stars of Kongming", which was mainly used for military strategy. In fact, whether the "Six Obsidian" was formed in the Three Kingdoms period is still inconclusive. Another view is that Liu Yao was created by Li in the Tang Dynasty.

Later, it spread to Japan, where it became popular and gradually declined in China. All versions have changed. At present, there are six versions: win first, led by friends, lose first, extinguish, Daan and Akaguchi.

The original version of six Obsids is slightly different from the current version. Daan, Ling Lian, Su Xi, Chikou, Xiaoji and Kong Wu are the six prostitutes in The Stone Forest.

Great Li Shu includes Tai 'an, lingering, red mouth, alms and virtual death. Later, it became "Daan", "Friendship", "First Victory", "Red Mouth", "First Bear" and "Buddha's Unique" in oral communication, and then it was deliberately changed into a popular version.
