Public information about Liu Yiqiang is currently limited, and details such as his birthplace, dates of birth and death, and educational background have not been clearly recorded. Judging from the holdings in the library, he has two works, Qiaoxing Haiyan and Qiaogui Dawang, both centered on the theme of qiaoxiang, or overseas Chinese hometowns, and both can be classified as historical reading and social science. The character qiao in the titles suggests an interest in overseas Chinese migration, social change in qiaoxiang communities, and the ties between emigrants and their hometowns. His writing tends to take specific localities as case studies, using historical sources and local contexts to present the historical memory and present situation of qiaoxiang. The similar themes of the two works indicate sustained attention and accumulation in this field. Owing to the lack of further verifiable information, his writing style and scholarly influence are difficult to assess fully, and readers may learn more about his narrative approach and use of sources by consulting the books themselves.
