Although the Forbidden City covers an area of more than 700,000 square meters, there are 70 deep wells in it, not including the sealed and abandoned ones. These wells are used for drinking and fire prevention. After the demise of the Ming Dynasty, many jewels were thrown into the deep wells of the Forbidden City. Why didn't anyone salvage it?
First of all, because these deep wells are Lock Longjing, there are underground ditches or underground streams under the wells, which are the sources of well water. Even some deep wells are directly connected with the underground river, so after the jewels are thrown into the deep wells of the Forbidden City, except for some extremely heavy gold and silver jewels, other lighter jewels like jewels will be washed away by the water of the underground river. Therefore, if the gem is dropped, it will be washed away by the water after a while and it is impossible to catch it.
In addition, the wellhead in the depths of the Forbidden City is very narrow, and people who are a little fatter will get stuck in the wellhead. If you want to salvage, you must use mechanical equipment. It is impossible to use machinery in such a narrow space. And some wells have been blocked by stones, and you need to dismantle them with large equipment to salvage them to the depths of the wells. This operation will destroy the ancient well, and even in the process of construction, landslides may occur, damage the wellhead and destroy cultural relics.
When the Qing Dynasty fell, the warlords allowed Puyi to continue to live in the palace, but did not give him living expenses. So the eunuchs in the palace will try their best to steal the treasures from the palace and sell them outside for daily necessities, so they will also salvage them in the deep wells of the Forbidden City. So the jewels that can be salvaged from deep wells will also be salvaged by them.
Then, after Cixi fled back to Beijing, although the Forbidden City was severely damaged and searched, Cixi would rearrange important treasures and salvage the treasures thrown in the deep well before fleeing, thus further reducing the treasures in the deep well.
