Ceramic pieces have a diameter between 20 and 30 cm and a length between 30 and 40 cm. At one end they are wider to fit and form long tubes. Once the pieces have been investigated, they have been deposited in the site, in its original location, where they will be best preserved. A few ceramic tubes have been rebuilt that have been deposited in various museums in China, such as the photo piece, in order to continue researching and showing it to the public.

Between 4,200 and 3,900 years ago, at a time of increasing flooding, the network of canyons and ceramic ditches for water transportation and drainage, the oldest in China, was able to build and maintain in collaboration and community work. The system required community-wide planning and coordination, but there were no centralized hierarchical structures in Pingliangtain. This shows that “the men of the Neolithic were able to perform complex engineering work without the need for central power, they did everything in a community way,” says archaeologist Yijie Zhuang.

In addition to the pipes, experts have investigated the traces of the houses of Pingliangtai and observed that all the houses were quite small and that there were no larger and more luxurious houses than among others. The cemetery has also been excavated, as the population hierarchy stands out in the objects that used to be buried along with the bodies in the graves, and no signs of social inequality have been found. The opposite is true in the fields of the same period. Both houses and tombs indicate that they were hierarchical communities. But these communities were not able to solve the problems posed by climate change.

Therefore, the Pingliangtai pipe shows that for the realization of complex engineering works a centralized power was not necessary. Moreover, a community without obvious imbalances had more capacity to address environmental challenges than a community with more “developed” command modes.
