The coming of the Warring States period brought an influx of Yuet people from the north into the area. They probably avoided the instabilities at the north and went south. Bronze fishing, combat, and ritual tools were excavated on Lantau Island and Lamma Island. Ma Wan was the earliest settlement with direct evidents in Hong Kong. Another one is Lung Kwu Tan. Bronze tools were found on Lantau Island, Cheung Chau, Chek Lap Kok as well. Regular holes on the ground were found in Ha Pak Nai. It is believed they were the foundations of grand houses of that period.
