At the beginning of the twentieth century, Pearl Buck came to Nanjing with her husband, Buck, and was employed by Jinling University (which was incorporated into Nanjing University in 1952) run by the American Church. She also lived in this small Western-style building with a single courtyard on campus. Here, Pearl S. Buck met Xu Zhimo, a gifted scholar, and deduced a passionate and painful love affair. However, the affair was terminated by a woman named Lu Xiaoman. Pearl Buck painfully hid her freshly derailed heart and sealed it with her letters. More noteworthy is that Pearl Buck, as an American female writer whose mother tongue is Chinese, wrote a novel "Earth" describing the life of Chinese peasants in this three-storey Western-style small foreign building. In 1932, the novel "Earth" won the Pulitzer Prize for fiction. In 1938, the novel "Earth" won the Nobel Prize for Literature. Pearl Buck is praised as a bridge between Chinese and Western cultures.
