Some scholars assert that the Hemudu culture co-existed with the
Majiabang culture as two separate and distinct cultures, with cultural transmissions between the two. Other scholars group Hemudu in with
Majiabang subtraditions. Two major floods caused the nearby
Yaojiang River to change its course and
inundated the soil with salt, forcing the people of Hemudu to abandon its settlements. The Hemudu people lived in long,
stilt houses. Communal longhouses were also common in Hemudu sites, much like the ones found in modern-day Borneo. The Hemudu culture was one of the earliest cultures to cultivate
rice. Recent excavations at the Hemudu period site of Tianluoshan has demonstrated rice was undergoing evolutionary changes recognized as
domestication. Most of the artifacts discovered at Hemudu consist of animal bones, exemplified by hoes made of shoulder bones used for cultivating rice. The culture also produced
lacquer wood. A red lacquer wood bowl at the Zhejiang Museum is dated to 4000-5000 BC. It is believed to be the earliest such object in the world. The remains of various plants, including
water caltrop,
Nelumbo nucifera,
acorns,
melon, wild
kiwifruit,
blackberries,
peach, the foxnut or
Gorgon euryale and
bottle gourd, were found at Hemudu and Tianluoshan. The Hemudu people likely domesticated
pigs but practiced extensive hunting of
deer and some wild
water buffalo. Fishing was also carried out on a large scale, with a particular focus on
crucian carp. The practices of fishing and hunting are evidenced by the remains of bone
harpoons and bows and arrowheads. Music instruments, such as bone whistles and wooden drums, were also found at Hemudu. Artifact design by Hemudu inhabitants bears many resemblances to those of Insular Southeast Asia. The culture produced a thick, porous
pottery. This distinctive pottery was typically black and made with
charcoal powder. Plant and geometric designs were commonly painted onto the pottery; the pottery was sometimes also cord-marked. The culture also produced carved
jade ornaments, carved
ivory artifacts and small clay figurines. ==Sociopolitical organization==
