Tell me about the major discoveries in archaeological history in the world?

On May 21, 1900, Wang Yuan, a Taoist priest who fled to Dunhuang Mogao Grottoes, was supervising hired workers to clean up the sand in the corridor of No. 16 Grotto under the Seventh Buddha. Taoist Wang knocked the crack with the pipe pot several times and found that it was empty. Under the excavation of hired workers, a scripture cave containing countless ancient scriptures, embroidered paintings, documents, magical instruments and other priceless treasures came to light.
