In December 1996-January 1997, three Eastern Han tombs at Ma'anling in Guigang City were excavated by the Guangxi Zhuang Autonomous Region Archaeological Team. Tomb M1 is a wooden-chambered rectangular earth shaft, M2 has a similar pit but no chamber, M3 is paved with bricks on the bottom, and each of them has a slanting tomb-passage. Among the funeral objects pottery vessels come first in number, bronzes next, and then some irons, silver articles and other artifacts. The pottery belongs mainly to the ding tripod, jar, pot, vase, gui food container, lian toilet box, bowl, hill incense burner, lamp, and house, well, granary and kitchen range molds; and the bronzes, to the bowl, dish, mirror and belt hook.
This is a Neolithic shellmound site 2km southwest of Jiangkou village in Baihe township, Hengxian county, Guangxi, on the first terrace by the right bank of the Yujiang River. Stone tools and pottery account for the majority of the unearthed artifacts; bone and shell objects occur in a small number. Molluscan shells were often discovered along with animal bones and teeth. The stone implements are principally polished at the edge or pecked on the whole body. The pottery is largely red sandy ware; some articles are of the black clay category. The vessels bear impressed coarse or fine cord marks and mostly belong to the fu cauldron and jar. The site shows a cultural aspect similar to that of the same type of shellmound in the valleys of the Yongjiang, Zuojiang and Youjiang rivers and dates from the mid Neolithic Age.
