Over 10000 boxes of national treasures from the Forbidden City have traveled thousands of miles on the path of war for many years. How can Chinese people protect their cultural heritage with their destiny? Zheng Xinmiao, former director of the Palace Museum, released a new book titled "National Memory: A History of the Southern Migration of Palace Museum Cultural Relics" in Beijing on the 14th, sharing the hardships for readers. He specifically pointed out that the special tasks and harsh environment have cultivated and formed the spirit of "treating national treasures as life" among the people of the Forbidden City. In February 1933, more than 13000 boxes of treasures from the Forbidden City were forced to embark on a southward migration. From Nanjing to the southwest, and then back to Nanjing from the southwest, traveling through half of China and enduring the hail of bullets, the loss of cultural relics was minimal. As the fifth director of the Palace Museum, Zheng Xinmiao spent four years writing this book, relying on a large number of archives, diaries, letters, and images to recreate the largest, longest lasting, and longest cultural migration in the history of world cultural relics in over 420000 words. The author depicts how a generation of Palace Museum residents such as Yi Peiji, Ma Heng, Na Zhiliang, and Zhuangsheng, with the spirit of "human presence in cultural relics", completed a silent and heroic treasure protection action and cultural resistance war. Looking back now, history has proven that there was no more effective way to protect cultural relics than southward migration at that time, "said Zheng Xinmiao. During her tenure as the director of the Palace Museum, Zheng Xinmiao actively promoted exchanges and cooperation between the Palace Museums on both sides of the Taiwan Strait. In his view, studying and promoting the history of the southward migration of cultural relics from the Forbidden City is an important task of the Palace Museum. The history of the southward migration of cultural relics from the Palace Museum is inseparable from the relationship between the Palace Museum on both sides of the Taiwan Strait. Part of the cultural relics were relocated to the south and transported to Taiwan, forming the current situation of "one Forbidden City, two museums". Gathering national treasures is not easy. Based on the sense of cultural identity of the Chinese nation that although there are two Palace Museums, there is only one Palace Museum, and the fact that the collections of the two museums are of the same origin and both are cultural heritage of the Chinese nation, it is the solemn and sacred historical mission of the two Palace Museums on both sides of the Taiwan Strait to strive to protect this rich cultural heritage and promote traditional Chinese culture, so that Chinese civilization can continue. ”Zheng Xinmiao said.
