What progress has Hemudu people made in life compared with Beijingers?

Six or seven thousand years ago, Hemudu area was still a swamp. When Hemudu people build houses, they first lay wooden stakes with a length of 1 m, and erect criss-crossing keels (ground beams) on the wooden stakes, and then lay floors with a thickness of more than 10 cm on the ground beams, and erect columns, beams and roofs on the floors. The floor plays a role in preventing moisture, insects and snakes. It can be used to feed livestock. This floor is the living room. From the height of the pillars, people can't go in and out upright, but many of them enter the life scene of Hemudu compared with nesting.
