What kind of person makes a fire with cow dung?

People can't make tea without cow dung as fuel except in the forest areas of Tibet Plateau. In old Tibet, the people had to pay various taxes to the lords, and paying dry firewood, dried cow dung cakes and other fuels was one of them. Trees are rare on the vast plateau in northern Tibet. Herdsmen keep company with cattle and sheep, and their excrement is their fuel. At that time, whenever herders saw cow dung, they would pick it up and dry it around the tent, even if it would stain their beautiful aprons. In this way, the dried cow dung will pile up into a hill. In snowy winter, there is a fire in every kitchen. In the evening, the smoke in the counting room fills the air, the dry cow dung burning in the furnace is soft, and the tea and meat cooked in the cauldron smell fragrant, which makes the people who come in feel warm and drooling at once. Herdsmen can't live without cow dung. Farmers are even more sophisticated. They mixed the picked cow dung with some hay, trampled them barefoot, made cow dung cakes of equal size and stuck them on their sunny courtyard wall, dried them and piled them neatly together. The more cow dung there is at home, it shows that this family is hardworking and rich. On winter nights, the family sat around the stove, and the burnt cow dung in the stove buried the children's favorite potatoes in the ashes. Everyone is drinking "Batu Ba Du" (Baba batter soup) with a hot mouth. The brazier next to it is filled with dried sheep dung, which is dark and reddish. A brazier is boiled tea or a pot of delicious mutton. The family tells the story of the day, tells old stories and sings some songs. What a happy picture. This city has changed again. Lhasa is bordered by Lhasa River in the south and there are several bare mountains in the north. The fuel used mainly comes from cattle and sheep manure in agricultural and pastoral areas and firewood in Linzhi in the east. In autumn and winter, herders drive cattle, and service cattle carry two bags of cow dung-from a distance, like piles of moving mounds-to transport cow dung from northern Tibet to Lhasa and give it to the government, temples and nobles. If there are too many, they will secretly sell them in the market or exchange some food and daily necessities. Later, a hydropower station was built in Lhasa, but there was no electricity. After the peaceful liberation of Tibet, the government has built many power stations in a planned way in places where conditions permit-hydropower stations, thermal power stations, geothermal power stations and pumped storage power stations, and some places have switched to electric stoves to cook tea. In the mid-1980s, the government built an oil pipeline from Lanzhou to Lhasa. Quiet, I don't know when to start. Many people in the city use kerosene, gasoline or diesel stoves to cook tea, which is convenient, clean and fast. In the 1990s, the national aid workers came from all provinces and cities, and everyone was making suggestions for the development of Tibet. Liquefied petroleum gas stations in Qinghai and Sichuan quickly set up sales outlets in Lhasa and surrounding towns, and clean liquefied petroleum gas cookers entered the homes of ordinary people. Urban residents have used new fuels that are sanitary, energy-saving and have strong firepower. Also, when you walk into people's courtyards or near herders' tents, you can see that the utilization of natural gas energy-solar energy given by nature is being vigorously promoted. Solar cookers convert light energy into heat energy, solar generators convert light energy into electricity, and solar water heaters make plateau people more energetic. Now, although the old mother who lives in the town still wants to build a stove that can burn cow dung and firewood in the kitchen, she has really retired. Using cow dung as fuel is a luxury-their prices in the market are staggering. Cow dung and solar energy are people in Xizang's favorite energy sources.
