There is a big underground river under the well, so it may be bottomless. So is the Forbidden City. Jewelry was thrown into the well of the Forbidden City. Except for some very heavy gold and silver jewelry, other lighter jewelry is easily washed away by the current of the underground river. So if you throw the jewels down, they will disappear for a long time and you can't get them.

The wellhead of the Forbidden City is very narrow, and a slightly fatter person may get stuck in the wellhead. If you really want to salvage, it is particularly difficult to use equipment and construction in such a narrow space. Many wells have long been blocked by stones, which need to be cleared by large machinery before they can be fished out in the depths of the wells. In this case, these ancient wells are likely to be destroyed, and even landslides are likely to occur during the construction process, which is also considered to be the destruction of cultural relics.
