Han Zuohai, a native of Han Ying Village, Huangdianzhuang Town, Changli County, Qinhuangdao City, runs a small printing factory in the harbor area. More than ten years ago, the reappearance of his hometown "Han Family Tree in Changli County" changed his life track. Looking at the names solidified in the genealogy, he felt a sense of historical responsibility: I am a descendant of Han Yu and should inherit the spiritual wealth of my ancestors and make some contributions to the present. So he began to continue to study the Han genealogy in Changli County, communicate with Han talents, and participated in the compilation of the World Han Genealogy. Recently, I have been busy running for the establishment of the Han clan association in Jidong.

The book was compiled by Wang Gong, the ancestor of Shang and Zhou Dynasties, and Han Feizi, a legalist, and then by the famous Han Xin, Han Yu, the head of the eight masters in Tang and Song Dynasties, Han Qi, a famous figure who assisted san huang in Song Dynasty, and Han Shizhong, a contemporary anti-gold hero of Yue Fei ... Among them, there are many outstanding representatives of Korea, in addition, there are overseas celebrities such as Singaporean Prime Minister Han and Malaysian Minister of Education Han Chunjin. As a descendant of Han Yu, Han Zuohai participated in the compilation of Han Family Tree in Changli County. After years of editing experience, Han Zuohai has looked around the world, met more outstanding Han people in the world, and learned more about Han's origin, which has benefited a lot. He said: "The revision of the score has the function of connecting the past with the future, which embodies the culture of filial piety and the morality of observing human relations, so that his son Sun Jingzu can be kind and the wisdom of his ancestors can shine, and Qi Xin will make more contributions to the country together."
