Why are China's coffins uneven on both sides, while foreign coffins are flat?

In modern times, the dead are cremated. In ancient times, the dead were buried, and coffins were needed for burial. Coffins can be made of different kinds of wood, such as pine and nanmu. The craft of making coffins is very complicated and pays attention to feng shui. Coffins in China are all high at one end and low at the other, while coffins abroad are all flat. What caused this difference? Is there any meaning in this?

In China, Feng Shui is very important. Coffin is the "haunted house" of the dead, and it is their home in another world. The house should have a slope of flowing water, and the coffin should be low at one end and high at the other, which is the principle of slope of flowing water. Slope water is to let the water from the roof flow down and not stay on the roof. The direction of the coffin underground is: the head points to the northwest and the feet point to the southeast.

? When you worship, you are always in the position of "feet" to show respect for the deceased. The coffins of foreigners are different from those of China. They are flat and have slightly wider heads. People there don't believe in yin and yang. They pay no attention to anything. It can be seen that customs are only regional, ethnic and religious, and there is no scientific necessity.

This is why China's coffin is high and low. In fact, China's coffins are not all high and low now, but also changing slowly. Many ideas are westernized, not as rigid as in ancient times. Funeral is a kind of culture, and sometimes we have to take its essence and discard its dross, find some old customs and spread new culture. When it comes to coffins, we all associate ghosts, fears and horrors. Actually, we don't think so, as long as we don't touch the bottom line. ?
