Yu Zongben is an author about whom little public information is available. Only one work by this name is held in the collection, Tianjia Li (The Farming Calendar). Since no clear records of his birth and death years, nationality, courtesy name, or life story have been found, it is difficult to sketch a complete personal history; only the surviving work can be briefly discussed. Judging from its title, Tianjia Li appears to be a calendar-type work related to farming seasons and the yearly cycle of rural life, likely touching on the timing of cultivation, the arrangement of solar terms, and everyday country living, with a practical and folk-knowledge flavor. In the collection it is classified under literary appreciation, perhaps because its plain and natural language preserves notable local customs and details of daily life within its farming records, giving it some value for reading and reflection. Overall, Yu Zongben's surviving works are few, and his name is known to later generations mainly through Tianjia Li; further research awaits the discovery of more documentary evidence.
