This couplet was given to the Zhang family in Licheng (now Jinan), Shandong Province, as a token of filial piety. The "3,000 pieces" in the couplets represent the Zhang family with a large population and profound cultural heritage. "Five Hundred Years of Filial Piety" emphasizes that the tradition of Zhang Jiaxiao has been passed down for hundreds of years and is a family model worthy of praise and inheritance. This couplet is a compliment to the Zhang family, and it also inherits and develops the spirit of "filial piety" in China traditional culture.
