We all know that when Cixi was in power, she especially liked to collect some gold, silver and jewels to her place of residence. Since Eight-Nation Alliance invaded Tsinghua, Cixi also put a lot of jewels and gold into deep wells to prevent them from being stolen. So later, after Cixi returned to Beijing, all these spilled treasures would be salvaged.
Later, after the demise of the Qing Dynasty, Puyi continued to live in the Forbidden City. At this time, ladies-in-waiting and eunuchs in the Forbidden City will naturally take the opportunity to resell some valuable small objects or gold and silver jewelry in the palace into cash. Naturally, they will not let go of some treasures that were once in the well, and of course they will salvage them as much as possible.
And most of the deep wells in the Forbidden City are very narrow. In fact, if you pour some treasures into deep wells and want to salvage them again, it is also very difficult. During the allied invasion of China, many deep wells have collapsed and are not particularly suitable for salvage. If compulsory salvage is carried out now, these deep wells may be destroyed, resulting in further damage to cultural relics.
