International students found that most of the traditional houses in Henan are caves, brick houses, slate houses and modern flat-roofed houses. According to relevant data, most of the traditional houses in Henan are caves, brick houses, slate houses and modern flat-roofed houses. The reason is that Henan's topography is plain, basin, mountain and hilly, with complex topography, high in the west and low in the east, and concave in the south of the north tower, which is only suitable for building caves, brick houses, slate houses and modern flat-roofed houses. This is also the most distinctive feature of Henan.
