The Gelao family likes to eat and drink Camellia oleifera, which is a traditional food custom of the Gelao nationality and an integral part of the "Sanyaotai" food culture of the Gelao nationality. "Yaotai" is a regional dialect in Zheng 'an, Daozhen and Wuchuan, which means "end". The first tea seat in Sanyaotai is mainly camellia oleifera, mainly drinking tea, accompanied by fruits and cakes. After the tea table, it is transferred to the second banquet, and the wine is the national wine or the corn wine brewed by the family; After the banquet, it was transferred to the third dining table. The most representative dish in the dining table is the shuttle meat of the nation, so the three dining tables are called "Sanyaotai", which is a food culture that has been passed down by the nation for thousands of years. This traditional diet custom not only has unique national characteristics, but also retains the primitive culture of the nation, which is unique among many ethnic groups in China. The custom of drinking Camellia oleifera has been inherited in Zheng 'an County for generations, mainly in Xinzhou Town, Yangxing Township and Bifeng Township, with a long history. Its production skills are mastered by every household in each village in China. The tea-picking song and dance "tea-picking song" and "tea-picking lamp" are still completely inherited in Pinggelao Autonomous Township of the city. The Yinzhen Museum in the county has a collection of the original tea-making tools, wooden tea kneading machines, which are also popular among the people today. The spreading area of the custom of making and drinking Camellia oleifera is not only widely spread among the people in Zheng 'an County, but also spread in some areas under the jurisdiction of neighboring Daozhen and Wuchuan counties.

As for the origin of Camellia oleifera, there is a story circulating among the people. It is said that thousands of years ago, the ancestors of Gelao people reclaimed land for survival, and often starved. When they were hungry, they picked tea tips and chewed them in their mouths, which was not only nontoxic, but also tasted bitter first, sweet later and fragrant again, and could satisfy their hunger temporarily. With the passage of time, Gelao people gradually turned this wild tea into home tea, raw tea into cooked tea, and tea into camellia oleifera, and called it "Gelao camellia". Since the family likes to drink camellia oleifera, they should make camellia oleifera well.
