The Xinglongwa culture (興隆洼文化) (6200–5400 BC) was a Neolithic culture in northeastern China, found mainly around the Inner Mongolia-Liaoning border. Xinglongwa pottery was primarily cylindrical, and baked at low temperatures. The Xinglongwa culture showed several signs of communal planning. At three Xinglongwa sites, houses were built in rows. Several Xinglongwa sites also featured a large central building. In addition, several Xinglongwa sites were surrounded by ditches.
The type site at Xinglongwa is located on the southwest side of a hill at Aohan Banner, Chifeng, Inner Mongolia; the site is named after a village 1.3 km to the southeast of the site. 120 pit-houses were discovered at Xinglongwa. Each home had a hearth at its center. Xinglongwa also featured a large building in the center of the village. Xinglongwa is the earliest discovered site in China to be surrounded by a ditch. Xinglongwa also featured an unusual burial custom, as some bodies were buried directly under the houses. Like other Xinglongwa sites, jade objects were also discovered. In the most lavish grave, a man was buried with a pair of pigs, as well as jade objects.
According to the study of 34 sets of human remains from Xinglongwa in-house burials, male individuals apparently predominate over female individuals at roughly 2:1 ratio (23 males vs. 11 females). Within the male group, no individuals were identified as being over 55 in age, whereas all of females belong to middle-to-old age group (no one younger than 35 years old). The youngest individuals examined were at age of 13 or 14 years old, so it's suspected that children before mature sex-awareness age might not have participated in in-house burial ritual if they die. From examined samples, the average height of male was between 163.8 cm and 168.8 cm, while the average height of female between 153.4 cm – 159.9 cm. Both male and female Xinglongwa individuals showed strong Mongoloid cranial features, and are thought to be the distant ancestors of the present-day Tungusic peoples.
