International students found that most of the traditional houses in Henan are cave dwellings, brick buildings, slate houses and modern flat-roofed houses. According to relevant information inquiry, most of the traditional houses in Henan are cave dwellings, brick-and-tile buildings, slate houses and modern flat-roofed houses. The reason is that the terrain of Henan is composed of plains, basins, mountains, and hills, and the terrain is complex. The terrain is high in the west and low in the east, with the north and south towers. The sunken area is only suitable for the construction of cave dwellings, brick buildings, slate houses and modern flat-roofed houses. This is also the most unique feature of Henan.
