What's the difference between traditional houses in the south and in the north? What is the reason?

Due to the cold winter in northern China, the characteristics of the house are as follows: the wall is thick, some are double-glazed, and there is a fireplace and fire resistance in the house, which is conducive to cold protection and heat preservation. Due to less annual precipitation, the roof slope is small; Due to the hot and humid climate in southern China, the characteristics of residential buildings are: tall and spacious houses are conducive to ventilation and heat dissipation, with large annual precipitation, and most residential buildings are sloping roofs, which are conducive to rainwater.

Therefore, the answer is: due to the cold winter in the northern region, its residential characteristics are: thick walls, some double-glazed houses, fireplaces and fire resistance in the house, which are conducive to cold protection and heat preservation, and the roof slope is small due to less annual precipitation; Due to the hot and humid climate in southern China, the characteristics of residential buildings are: tall and spacious houses are conducive to ventilation and heat dissipation, with large annual precipitation, and most residential buildings are sloping roofs, which are conducive to rainwater.
