Digging Into the Past

It was a day in October 1921 that a tall foreign man appeared in the small village of Yangshao, in Henan Province of central China. This Swedish geologist, Johan Gunnar Andersson, had originally been invited to China as a mining adviser in the 1910s. However, a few pieces of pottery brought back from this village by his Chinese assistant made him suspect the existence of something more precious than mines.
