Lao Liang: Why can't the mausoleum of the First Qin Emperor be excavated?

The reason why the mausoleum of the First Qin Emperor can't be excavated is because there are still many blind spots in science and technology, which can't completely preserve underground cultural relics. Therefore, once the cultural relics are excavated, they will be deteriorated or weathered due to the strong oxidation of oxygen.

This is mainly due to the active excavation of the Ming Tombs, which led to a large number of cultural relics being oxidized or weathered and suffered heavy losses.

Therefore, it was later decided that imperial tombs generally did not take the initiative to dig for future generations. Only those that have been stolen or damaged by construction shall be excavated for rescue.

This is mainly the right decision to protect cultural relics.
