Nine-headed Cooper is considered as the top grade, followed by others. There are Korean pine and white pine, followed by paulownia. The price is cheap and can't stand corrosion. Due to different conditions, the situation varies greatly across the country. This is just a personal opinion, for reference only. Sandalwood has strong corrosion resistance. 1987 unearthed in Huai' an county, Jiangsu province, the tomb of Wang Zhen's husband and wife in the Ming dynasty, with the same style as the coffin. Just because Wang Zhen's sandalwood coffin was still intact when it was excavated, and his wife only had bones, because the coffin was not made of sandalwood.
After the death of the ancients, nanmu coffins were generally used, because nanmu has the function of anticorrosion and moisture absorption. The poor use cypresses, etc. Later, the surface of the coffin was painted with waterproof paint, depending on the terrain and cemetery structure. Modern coffins generally include cypress, lacquer and sandalwood. In history, Nanmu, Cinnamomum camphora, Catalpa bungeana and Nanmu were called the four famous trees, and Nanmu was called the first, which shows how much people like Nanmu. In China, nanmu has always been regarded as the most ideal, precious and advanced building material, which is widely used in palaces, gardens, temples and tombs. A thousand-year-old cedarwood and a thousand-year-old fir (wood) have made people and made money. Many people here like 36 -40 cm fir.
