Zhou La'er realized he had been distracted and hurriedly said, "Father, Zhao's mother was sold in Pingzhou many years ago; all we know is that she was bought by a family with the surname Yun. I've made inquiries twice but haven't found anything, so I was hoping you could help look into it to see if there is a prominent family with the surname Yun in Pingzhou City."
Zhou Shuren asked, "Just the surname?"
Zhou La'er knew the information was too scant, "Just the surname."
Zhou Shuren thought to himself that there weren't many with the surname Yun, and those who could afford servants must be wealthy households. Although Pingzhou City was not small, the Zhao family was an old clan in Pingzhou, and there was nothing in Pingzhou City that the Zhaos didn't know about. Asking Zhao Bo should yield some results, "I've noted it down. I will have someone look into it. You all wait for the news."
Zhao's anxious heart settled, and she knelt down in gratitude, saying, "Thank you, Father."
