The Fenglin city-site lies in a spot of low flood land on the northern bank ot the Qixing River, about 300m west to Fenglin village of Chengfu township in Youyi county, Heilongjiang province. It is the largest among the Han-Wei period city-sites known so far in the Three Rivers Plain. In 1998, the Heilongjiang Provincial Institute of Cultural Relics and Archaeology carried out excavation in the seventh city-area of the site, which resulted in the revelation of eight house-foundations, 23 ash-pits and nearly 300 objects. The main remains are of a relatively late date, i.e. later than the Tuanji and Guntuling cultures, and belong to the Wei-Jin period.
