What does Wuri mean?

The stem and branch chronology is composed of ten heavenly stems (Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui) and twelve earthly branches (Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu, Hai). There are 60 combinations in total, which are called a Jiazi cycle. Wu Day appears every 10 days in the zodiac calendar and has specific cultural meanings and folk customs.
