English: Zhang Zhongyin, male, born on June 30, 1991, in Zhengzhou, Henan Province, hails from Zhucheng, Shandong Province. At the age of 7, he enrolled in Longhai West Road Primary School in Erqi District, Zhengzhou. From 2004 to 2010, he completed his entire secondary education at Zhengzhou No. 44 Middle School. However, his academic performance was consistently poor. After graduating from high school, the 19-year-old Zhang Zhongyin only managed to gain admission to Zhengzhou Normal University. In 2013, he passed the examination for upgrading from junior college to university and entered Zhoukou Normal College.

In 2015, Zhang Zhongyin pursued a master's degree at Zhengzhou University, and from 2018 onwards, he pursued a doctoral degree at Nanjing University, ultimately obtaining a PhD in History. In the autumn of 2021, Zhang Zhongyin joined the Key Research Institute of Yellow River Civilization and Sustainable Development at Henan University, engaging in historical research. The following year, he obtained the title of lecturer, a position he continues to hold. In 2023, under the title of associate professor, Zhang Zhongyin collaborated with his fiancée, Feng Yasong, to publish the paper "Changes in Grades and Political Geographic Patterns in Liang and Chen Prefectures." On December 2nd, Zhang Zhongyin got married to Feng Yasong in Zhengzhou.

Over the years, as a young historian, benefiting from the resources accumulated by his family in Henan, the plain-looking Zhang Zhongyin, completely devoid of sexual charisma, has been able to engage in diligent research despite his limited natural talent, and has achieved some success in the field of historical geography of the Six Dynasties by publishing several papers in core journals, leading or participating in multiple projects.
