The Bourau nationality, formerly known as the Zhuang nationality, is a minority with the largest population in China. The national language is Zhuang, belonging to the Zhuang Dai branch of the Zhuang Dong language family of the Sino Tibetan language family.
The Zhuang nationality originated from "Xi'ou" and "Luo Yue" in the Lingnan area recorded in Han historical records in pre-Qin, Qin, and Han Dynasties. It is distributed in 31 provinces, autonomous regions, and municipalities directly under the central government in China, mainly in the south, starting from Lianshan Zhuang and Yao Autonomous County in Guangdong Province in the East, Wenshan Zhuang and Miao Autonomous Prefecture in Yunnan Province in the west, and Congjiang County in Qiandongnan Miao and Dong Autonomous Prefecture in Guizhou Province in the north, South to Beibu Gulf. Guangxi Zhuang Autonomous Region is the main distribution area of Zhuang nationality.
The Zhuang people in most areas are used to eating three meals a day, while the Zhuang people in a few areas also eat four meals, that is, a small meal is added between lunch and dinner. Breakfast and Chinese food are relatively simple, generally eat porridge, dinner for dinner, eat dry rice, dishes are more abundant. Rice and corn are the main food of Bourau nationality. Zhuang people can't help eating livestock meat, such as pork, beef, mutton, chicken, duck, goose, and so on. Some areas don't eat dog meat, while others love dog meat. Pork is a whole piece of first cooked, then cut into square pieces, back to the pot with seasoning. Zhuang people are used to making fresh chicken, duck, fish, and vegetables into seven or eight mature dishes. The dishes are stir-fried in a hot pot and then out of the pot, which can maintain the freshness of the dishes.
March 3 is the most solemn festival of Zhuang, Yao, Miao, Dong, Mulao, Maonan, and other ethnic groups in Guangxi. In 2014, it was determined as a traditional festival in Guangxi and had two days off. among them, the "March 3" Song fair is popular in Zhuang areas, especially in the Hengshui River and Zuojiang river. The number of people in each fair ranges from a few hundred to thousands or even tens of thousands. In Zhuang, Yao, Miao, Dong, and other minority areas and some Han areas, on the third of March of the lunar calendar, every family makes five-color glutinous rice, dyes colored eggs, kill chickens, and ducks, drinks wine, and celebrates the festival in different ways. Some places are more prosperous than the Spring Festival. before the festival, every family prepares five-colored glutinous rice and colored eggs. Red orchid grass, yellow rice flower, maple leaf, and purple Fanteng are collected and soaked in the juice of these plants to make red, yellow, black, purple, and white glutinous rice. According to legend, this kind of food was passed down after being praised by the fairies, and some people said that it was offered to the singer Liu Sanjie. After eating this kind of food, people are prosperous and healthy. Zhuang family love five-color rice, as a symbol of happiness and auspiciousness. On happy days such as the children's full moon and the completion of their new home, they also cook colorful meals and send them to their neighbors. Zhuang people also love maple leaf and think that maple leaf can "remove evil spirits" and bring good luck and peace to people.
In Buchanan, Daoxian county (the active area of the Cangwu tribe of the ancient Zhuang nationality), the weaving pattern of plant fiber, which was used to make "bedding cloth" for pottery 15000 years ago, was discovered. It is the first handmade textile created by human labor so far.
Zhuang clothing referred to as "Zhuang clothing", mainly has three colors: blue, black, and brown. Zhuang women have the habit of planting cotton and spinning. Spinning, weaving, and dyeing have become a household handicraft industry. The cloth woven from self-planted and self-spun cotton yarn is called a "home machine". It is fine, thick, solid, and wear-resistant, and then dyed blue, black, or brown. It can be dyed into the blue or cyan cloth with big green (a kind of herb), black cloth with fish pond deep, and brown cloth with Dioscorea Cirrhosa. There are different costumes of Zhuang nationality. Men's and women's costumes and men's, women's, and unmarried women's headwear have their own characteristics.  There are two kinds of men's clothing: right front and double front. The right front has no collar on the back. The buttons open from the right armpit to the waist and then turn to the center, and then open three or four inches. The skirt is inlaid with more than one-inch wide colored cloth edge, with copper buttons, and then put on a long belt. The double front is open, and the length is only up to the navel.
Women's wear has no collar and right skirt, but the sleeves are larger than men's wear. They are nearly one foot wide and knee long. They are inlaid with them. The hem is wide and thin, generally more than two or three. The inside of the shoulder is pasted with the cloth to set off the outside, and three stitches are sewed, which is called a "shirtless shirt". The buttons of men's and women's shirts are copper buttons or cloth buttons. Men's and women's trousers are basically the same in style, with a hem at the bottom, commonly known as "croissants". A married woman has a lace-bellied pocket. A spike-shaped tube is hung on the left side of her waist pants, which is connected with the key. When she walks around, it makes a "Sha La Sha La" sound. Men's formal dress is used to wearing long robes with a short jacket on the outside, which is commonly known as "long gown with Chinese jacket". At first, they wore a round hat and later changed to a top hat. Both men and women wear cloth shoes.
Both men and women wear cloth shoes. Middle-aged women like to wear their own cat's ear cloth shoes when they go to work in the mountains. They are commonly known as shoe cats. They look like straw sandals with ears and heels. They use a flat ribbon to string the ears and heels together, and they can adjust the tightness at will. Children's headdress: the children's hat is made of two or three-inch wide embroidered cloth. In ancient books, it is recorded that Zhuang customs such as "bare top and bare feet" and "cloth and silk Le Er (tie ER)" are reappeared in children's hats. This kind of hat can not only protect the head but also be a kind of decoration. The baby's back belt is much larger than the common Han nationality's, which is butterfly-shaped. The "butterfly body" is three feet long and two feet and four inches wide, and embroidered with patterns or eight trigrams. But rarely embroidered with words, the "butterfly wings" on both sides are nine feet long and one foot and two inches wide. This kind of back belt is called "lap" in the Zhuang language. After the founding of the people's Republic of China, the size of the strap was gradually reduced. Some of the straps were embroidered with words such as "safe in and out" and "happy" instead of the original pattern.
