Emperor Qianlong reigned for 60 years, and his collection of rare treasures was several times more than the sum of the five emperors before the Qing Dynasty. Even after he abdicated, he became the emperor's father for more than three years and regarded finding antiques as a business. It is conceivable that there are many funerary objects in the grave after his death.
No wonder Commander Sun Dianying chose to steal the tomb of Qianlong. Most of the stolen treasures are unaccounted for or even lost overseas, and several of them are very popular with Qianlong, and they are priceless and have experienced twists and turns. But the problems left over from history cannot be solved in one or two sentences.
Moreover, there are not a few cultural relics lost overseas. I hope that through the efforts of all walks of life, the treasure that has left the motherland for many years will return as soon as possible.
