Even in Yunnan, which is rich in customs and folk customs, Jiangcheng is also a very special one - this small town is called "one city with three countries", which is the only county in Yunnan bordering Laos and Vietnam, with a border line of 183 kilometers. Such a small town, the local customs and customs naturally have its own unique features. The Sanzhai Village, the town of the whole Dong Town, which we went to in the south of Jiangcheng, is very special. It used to be the transit station of the caravan. Very prosperous. Step into the village, as if stepping into the paradise of Tao Yuanming's pen, the village is not big, but it is very clean, the cement road in the village is very clean, and the space between the buildings is also very large. Sense. The Yi people lived in the bamboo building for 1400 years, mostly on the first floor and the bottom. The ground floor is generally used as a warehouse. Almost every household has a string of corn, a scene of harvest. The Yu village is built on a gentle slope next to the forest. Papaya, carambola and jackfruit are planted on the roadside. There is also a temple full of Yi people in the village. The Yi people are hardworking and kind, and people are drying corn in the village, peeling off bamboo shoots, and having fun with their grandchildren. Where is the most happy place in China? This answer can be said to be different, but in Jiangcheng, I really feel the leisure, comfort and happiness of the village. The villagers we met all had a warm smile - it was a sincere smile, not because everyone here was full of money, but from the pure blue sky here, the fresh air, the full green , sweet fruit, and a heart of contentment.
