Morrison's library is an important cultural achievement that he has influenced so far. Mo Li Xun himself attaches more importance to it than anything else. After buying Wangfujing Mansion, he completely transformed the original building. According to his good friend Lian Dewu, the south wing is the library. The library is about 4 meters high, 6 meters wide and 25 to 30 meters long. Without pillars. The beams and zenith are all cast with cement, which is not the traditional wooden structure in China. Mo Lixun decided to sell it at 19 12 because it was difficult for him to maintain this expensive hobby in energy and financial resources. He proposed that "if China people buy it, I will give my property in Beijing, that is, the library with fire prevention equipment, to the government". Zhang Jian once inquired about the price, but there was no following. Mo Lixun said: "I had hoped that it could stay in Beijing, but it couldn't." 19 17 years, he sold his books to Baron Iwasaki Jiugong in Japan, so that he could at least stay in Asia. Today, Mo Library has become an integral part of the Oriental Library.
