"Business isn't good? Or are you saying I'm no good?" Xia Zheng raised his eyebrows.
Shopkeeper Wu had not spent as much time with Xia Zheng as Shopkeeper Liu had, so naturally, he did not understand Xia Zheng as well as Shopkeeper Liu did. If Shopkeeper Liu were here, he would have realized right away that Xia Zheng was actually just teasing Shopkeeper Wu for fun.
Lin Yuan pulled Xia Zheng aside, laughing, "Enough, stop teasing Shopkeeper Wu. Today is a rare joyous occasion, and yet you insist on scaring Shopkeeper Wu witless."
Xia Zheng giggled and, indeed, stopped talking.
