Some brass artifacts were also found, the oldest copper artifacts found in China. The total area of the site is estimated at 50,000 m2, and consisted of a village with around 100 homes.The homes were built with simple materials, for example, bamboos. People then knew to put a roof for their houses and rooms for other uses just like modern day houses.
