Why has a house with a thatched roof become a scenic spot?

Besides tiles, roofs in rainy and humid areas also have many other materials adapted to local conditions. For example, it is also beautiful and practical to use flat natural thin stone slices as tiles in Guizhou mountainous areas; In some mountainous areas, splitting thick bamboo and connecting bamboo joints are long tiles, so there is no leakage of rain in the house; Citronella in Xishuangbanna, Dehong Autonomous Prefecture, palm leaves in East Timor and coconut leaves in Western Samoa are also inexhaustible roof materials. On the contrary, although there are tile-topped areas in the arid northwest of China (for example, Ningxia), there are only raised tiles without covering them. Because there is little rain here, there is not much rainfall, and there is no shortage of roofing.

In particularly wet and rainy areas, the eaves are often extended for a long time, or the shape of the roof is changed from a straight line to a curved line, that is, from the top to the eaves, it is steep first, then slow down, and finally slightly tilted up, which can make the roof rain shoot farther, that is, the so-called "spitting water (fast) and slipping away". In more rainy areas, rain troughs are installed under the eaves to guide water centrally, and the foundation of the house is raised, which can prevent the eaves from eroding the wall foundation. In areas with heavy rain and long duration in Japan, in order to prevent water seepage from tile edges, mortar is used to coat the joints of tiles and increase the slope of the roof to reduce the residence time of rainwater on the roof.

areas that are flooded seasonally, such as around Phnom Penh Lake in Cambodia, Tongtamei Plain in Mekong Delta and Qianhoujiang Plain, are land of plenty for farming in dry season and fishing in rainy season. Farmers in these areas all live in high-rise houses. They can go upstairs and downstairs in the dry season, and the water is the threshold in the rainy season. They have a unique way of living by boat.

Actually, it is not necessary to have high-rise water houses in areas where seasonal flooding occurs. In tropical Africa, there is a floating village, Gonviere, on Lake Noccu near Cotonou, the largest city in Benin and China. It attracts tourists from all over the world who have lived in high-rise buildings on land for a long time with its unique floating house architecture and primitive lifestyle, making it the top three scenic spots in Benin and a tourist attraction in West Africa.

High-rise houses in Cambodia are located in tropical cities with high temperature and rainy weather, and there are also many buildings adapted to this climate. One of the most typical ones is the pedestrian corridors (commonly known as arcades) on both sides of the street. It can be seen in many cities along the southeast coast of China, such as Xiamen, Shantou, Guangzhou and Nanning. The shops and buildings on both sides of the street extend from the second floor to the sidewalks in the direction of the street center, so as to avoid the direct exposure of tropical sun and solve the problem of rain shelter for pedestrians and customers. Many small and medium-sized towns generally have buildings that extend eaves to form pedestrian corridors, such as pillar-supported pedestrian corridors in Zhangping, Fujian and Meixian, Guangdong, and pedestrian corridors in Longyan, Fujian are supported by arches instead of columns, which look like long arch bridges on both sides of the street from a distance. Because of this kind of pedestrian corridor, many tropical city residents often go out without rain gear.

Although the precipitation properties of the rain and snow in the south of China are different, there are many similarities between the effects of heavy rain and Zita Law on housing. For example, in snowy areas of the world, the thickness of snow on the street can be no one's head. On the west coast of Honshu, Japan, which is on the windward side of the northwest monsoon in winter, it is one of the snowy areas in the world. In winter, many cities have to add temporary walls under the extended eaves to form closed pedestrian corridors, such as Nagaoka City and Takada City, which have a lot of snow in winter, and there are also special wooden pedestrian corridors called "Wild Goose Wood". In Japan's mountainous areas with deep snow, most houses have two floors. In winter, the ground floor is surrounded by snow, and you can also take the stairs outside the house directly and get in and out from the second floor.

In addition, in areas with heavy snow, houses will be damaged due to heavy snow pressure. Therefore, in addition to strengthening the roof, such as strengthening the rafters and adding support to the eaves, the slope of the roof is generally steep to minimize the snow on the roof. Medieval spire houses in mountainous areas of Central Europe and northwest Europe are related to the snowy climate.
