The Suzhou museum is running an exhibition of works collected by the Pan family of Suzhou, the lineage responsible for producing the most number of scholars in South East China, maybe incomparable even on a national scale.
The documentary being featured tells a story of how the Pan family managed to hide two 3000 year old cauldrons from the invading Japanese during WWII, and later on they donated both of them to the national archive.
