Why is there a big difference between the structure of a dry-fence house and a semi-cave house, which is about 6,000 years old?

Because the people who built them were different, and the regions were different, in the Yellow River basin and the Yangtze River basin Because the houses were built according to the climate, the climate in the south and the north were different, so the difference was big Well I just learned it, so I'll share it

Dry-fence style:

Located in the south, with a humid climate and many mosquitoes, the houses had to be built very high, and the open space underneath could be used to raise animals.

Semi-cavern type: located in the northwest, the climate is dry, semi-cavern houses can block the sand and sunshine, cool
