The most valuable treasure in Qianlong's mausoleum is the Dalagni Sutra wrapped around him. At that time, Sun Dianying didn't pay much attention to this quilt when he was digging the Qianlong Mausoleum. At that time, his eyes were focused on ordinary jewelry that he could see. Because Sun Dianying was nearsighted, he missed this priceless treasure. At that time, when Sun Dianying bombed Longling, all the gold, silver and jewels in the tomb were taken away, and even several private paintings with collection significance were all torn up. At that time, the quilt covered on Ganlong looked like a rag to Sun Dianying. But Sun Dianying was wrong. In fact, this Buddhist sutra is of great historical significance. At that time, Sun Dianying saw this quilt and ordered the soldiers to pick all the pearls on this quilt and throw them away at will. Now people should thank Sun Dianying for this order, otherwise such precious wealth will be destroyed. It is said that this quilt at that time should be priceless from any angle. There are always two quilts found during a robbery in Sun Dianying. 1 Empress Dowager Cixi was buried, and the second emperor Qianlong was buried. Because the technology of this quilt is very complicated, it can be said that it was made by combining many technologies at that time. It is the private collection of Emperor Qianlong, and it is also customized through the unremitting efforts of many workers. The main material of this quilt is silk reeling, which has become a royal item in the Yuan, Ming and Qing Dynasties. At that time, it was too precious for ordinary people to find. So this quilt is actually a status symbol. If we study this quilt from a cultural perspective, we will find that Guru King Kong carved 72 kinds of spells on it at that time. This kind of quilt is mainly used to praise the merits and demerits of the monarch. Therefore, this quilt can be said to be priceless in terms of cultural value or material value. At that time, this kind of quilt had very rich historical research value and very elegant materials.
