The site at Wucheng was a regional protoporcelain production center; the culture is known for its distinctive geometric pottery.

The bronze axes were similar to those of the Dong Dau culture in the Red River valley.

Towards the end of the Erligang culture, Wucheng began to grow significantly, while Panlongcheng declined sharply.
