Most construction and upkeep take place during the first several centuries of the Liangzhu culture, only limited upkeep is pursued from ~4600 BP, and none is documented after ~4500 BP. Note that the wet phase at ~4300 BP, when the Liangzhu culture ends, is not ‘higher’ in comparison to peak wet periods in the past.
