Does anyone use an iron coffin?

Nobody uses iron coffins. In ancient times, bronze coffins were either evil or evil. Normally, iron coffins are not used. Burying a copper coffin is very easy to hide a corpse, which is not only bad for future generations, but also takes a long time. Given the geographical location of the burial site, problems are bound to arise. The coffin, also known as the old house, is specially designed for the dead, and its workmanship is very fine. Mainly made of popular conifers and cypresses, especially exquisite coffins made of precious nanmu or natural crystal stone. And its shape is also very strange, with a big front end and a small back end, which is stepped. The inclined plane of each board used is opposite, and each part after molding should also reflect the inclined plane which is big in front and small in back. The so-called coffin material is also called inclined cargo material, but both sides and lid are inclined with radians. From the front of the material head, the whole coffin looks like a semicircle.
