The Chinese Civil War resumed following the surrender of the Japanese, ultimately resulting in Generalissimo Chiang Kai-shek's decision to evacuate the arts to Taiwan, which had been handed over to the ROC in 1945. When the fighting worsened in 1948 between the Communist and Nationalist armies, the National Beiping Palace Museum and other five institutions made the decision to send some of the most prized items to Taiwan.[11] Hang Li-wu, later director of the museum, supervised the transport of some of the collection in three groups from Nanking to the harbor in Keelung, Taiwan between December 1948 and February 1949. By the time the items arrived in Taiwan, the Communist army had already seized control of the National Beiping Palace Museum collection so not all of the collection could be sent to Taiwan. A total of 2,972 crates of artifacts from the Forbidden City moved to Taiwan only accounted for 22% of the crates originally transported south, although the pieces represented some of the very best of the collection.
