When buried, the coffin also has a specific orientation, with the big head facing north and the small head facing southeast. Therefore, the design of coffins is not only high and low, but also big and small heads. When we worship them, we should also bow down to our heads, which is a respect for the deceased. The theory of Yin-Yang Feng Shui is the characteristic culture of China, but there is no such statement and stress in the west, so their coffins are different from ours.
Due to the cultural differences between China and the West, there are differences in all aspects. People in China have always had the saying of Feng Shui. For example, some people pay attention to building houses, doing business and funeral. After death, people will ask some Yin and Yang teachers to choose a specific date and time for burial and so on. Although there is no scientific basis, it is the cultural heritage of China.
Since the emergence of human beings, there have been special feelings and attitudes towards death. Everyone knows that people can't be resurrected after death, but people still try their best to express their grief for the dead. For example, every year, Tomb-Sweeping Day pays homage to his ancestors, and on New Year's Day, besides visiting relatives and friends, he gives incense to the deceased. The most important thing after death is the placement of the body, so people made all kinds of coffins.
