In 2007, the famous Columbia University in the United States launched a search notice, they were looking for a Chinese more than 100 years ago. What kind of person, with such a strong appeal, can make the famous Universities in the United States look around a hundred years later? You may not believe it, this person is a illiterate person with big characters, this person's name is Ding Long. Speaking of Ding Long, many people said that they had never heard of it. It is no wonder that in this life, he left no property and no heirs.

After the 1870s, hundreds of thousands of Chinese workers were lured to the United States by Western capitalists to serve as cheap labor. Because Chinese workers are hard-working and labor costs are very low, they have greatly impacted the local labor market. Ding Long was a very ordinary one among these thousands of Chinese workers. After spending some time in Los Angeles, he became a servant of General Carpentier. After serving Carpentier for many years, Carpentier once asked Ding Long what he wanted to get in return for his loyal service for so many years. Ding Long's answer was unexpected, and he asked the master to donate every penny of his lifelong hard-earned money to a famous American university, and asked the university to establish a department of sinology to study the culture of his motherland.
Although in the eyes of many people, Ding Long is just a low-status servant, but in Ding Long's heart, even if he is far away from home, he still has not forgotten to spread Chinese culture abroad and let more people learn profound Chinese studies, although his donation is only a dime. Chinese the news of the establishment of the Department of Sinology in a famous american university spread out, it immediately caused a sensation in the United States, and even spread to China on the other side of the ocean, and the Qing government at that time was also touched by Ding Long after hearing Ding Long's deeds, and Empress Dowager Cixi personally donated more than 5,000 precious books, including "The Integration of Ancient and Modern Books in King's Dynasty"; Li Hongzhang and Wu Tingfang, an envoy of the Qing government in the United States, and others donated. Academics such as Hu Shi and Fu Sinian have left footprints in this department.
Ding Long left New York on June 27, 1905, and returned to China the following year, after which the clues to his life were completely interrupted. So many years later, Columbia University in the United States launched a search notice about Ding Long, and there was no clue for a long time. This ordinary person who once left Chinese culture in the United States did not tell the world because of his contribution, and he did not leave a trace of the world. As a descendant, we should remember his dedication to Chinese culture, and now the world has set off a "Chinese tide" to promote Chinese culture to the world, and we have an unshirkable responsibility!
