Besides herbal baths, how much do you know about the customs of the Yao people?

The Yao people call themselves 'Mien', 'Mun', 'Bunu', and others, their ancestors being part of the Wuling barbarians (Wuxi barbarians) during the Qin and Han dynasties. The Yao families live in a pattern of 'broad dispersion and small settlements', generation after generation scattered across steep mountains and ridges. The Yao is one of the ethnic groups in China with the most branches. They use the over 3000-line 'Song of King Pan' to narrate the formation of all things and interpret the hardships of creation. Yao men generally hold their coming-of-age ceremony—the 'Du Jie'—around the age of fifteen during the Panwang Festival. Young Yao people have to undergo nearly ten kinds of dangerous and painful tests, such as jumping on the cloud platform and the most common ritual of walking barefoot 'up the knife mountain, down the fire'. The Yao people have many traditional festivals, such as the Shejie, Panwang Festival, 'Zhu Zhe Festival', 'Shua Wang Festival', etc. The Panwang Festival on October 16th every year is a folk festival that combines ancestor worship, entertaining deities, and joy for the people. Yao compatriots gather together to worship King Pan, sing the Song of King Pan, dance the yellow mud drum dance and the long drum dance, to thank King Pan, and to praise the spirit of their ancestors' brave struggle. The Yao people in Liuzhou have the custom of washing in a 'Pang Tong Liang'. A Pang Tong is a huge fir wood bathing tub, usually used with hot water, but if there are distinguished guests, boiling herbal soup is added. Young men and women engage in free love through singing duets and climbing towers. Some settlements still retain primitive forms of social organization, such as 'Ba Yin', 'You Guo', 'Yao Lao System', and 'Stone Tablet System'. The Stone Tablet System is a spontaneously organized social organization based on geographical relationships. The head of the stone tablet organizes 'Hui Shipai' (stone tablet meetings) to deal with disputes and resist foreign enemies, etc.
