Bisezhai Village is located in the south of Caoba Town, Mengzi County, Yunnan Province. Mengzi is the heart of southern Yunnan Province. Bisezhai Railway Station is the witness of the brilliant commercial era of Mengzi County in the early 20th century and Yunnan's pride. After a hundred years, this small railway station still welcomes 20 trains from Yunnan-Vietnam Railway Station every day. Occasionally, there are passengers hitchhiking. There is a small village near the railway station, which existed before the railway station, originally named "Poxin", but because a French official stationed in Montezuela found the beautiful scenery of the mountain and sea, named "Bise Zhai", the village was named after the railway station and the same name. With the opening of Yunnan-Vietnam Railway, Bise Village, which had only a dozen households at first, became a special station on the railway line, quickly became a very busy transit station and trade fair, and became an important distribution center of Yunnan's import and export trade.
