However, China people should know that China pays attention to Feng Shui, and the coffin is the "haunted house" of the deceased, that is, his (her) "house" in another world. And the house should have "sloping water". In the eyes of the ancients, one end is high and the other end is low, which means "inclined water". With sloping water, the rain falling on the "roof" can stay smoothly, just like leaving him in the sun. So this is a good wish and respect for the deceased.
Unlike China, early European and American countries were more open-minded, not superstitious and believed in science. Because the progress of European and American countries in the ideological field is faster than that of China, the coffin designed is flat and the "head" is a little wider than that of China, but it can be seen that this has a lot to do with the regional environment and social atmosphere at that time.
In short, in the final analysis, it is because the social living environment, geographical environment and cultural customs of different countries are different. China's coffin is high and low on both sides because people in China believe in Feng Shui and are superstitious. They hope that their loved ones can lie down with peace of mind and comfort after their death. The design of one height and one height is their good wishes to the deceased. Coffins in European and American countries are flat, because foreigners are not superstitious, do not believe in geomantic omen, and do not pay attention to it.
