     During the Kuomintang era, he hid his collection suspected of being "pro-Communist" under the roof tiles. During the Cultural Revolution, his home was ransacked, but since he had handed over his collection to the museum for safekeeping a few days earlier in a mountain cave repository, the collection was spared. In 1979 Shanghai Museum returned it intact to Mr. Wu. Appreciating their careful preservation, the old gentleman donated over 5,000 valuable pieces to the museum.
