Bajiaolou is located in Xiankeng Village, Dongyuan County, Heyuan City, Guangdong Province. Built in Qing Dynasty, it is a large-scale and representative Hakka enclosed house. ? More than 260 years ago, an old man named Ye Benyu spent tens of thousands of taels of silver after he retired from politics during the Qianlong period. It took 16 years to build a four-corner castle-like building, with a watchtower at each corner, commonly known as the four-corner building. In order to ensure the infallible resistance to the enemy, a double safety protection wall was built on the periphery, and a watchtower with a height of 10 was set at each corner. The thickness of retaining wall is about1.7m.. Because they are all made of hemp and stone, the locals call it stone building.

Bajiaolou, as the earliest ancient residential building in Xiankeng Village, is the earliest and most defensive Hakka residential building in Dongjiang River Basin. It is an ancient building with Hakka and military characteristics and is listed as the seventh batch of cultural relics protection units in Guangdong Province.
