Zhang Yun, armed with his eloquent tongue and his handsome face, persuaded Yuewan, successfully sought a marriage arrangement through Su Rong, and swiftly had their son, Xiao Zhang Zhou.
However, he indeed fulfilled the promise he initially made to Yuewan, ensuring she could enjoy his provisions—eat his food, drink his drink, live in his house.
