Zhuang Qingning had heard about people keeping strands of hair in their wallets.
Perhaps there was some kind of explanation - they were kept to ward off evil spirits, or maybe they belonged to someone the maid loved but could not have, so she kept their hair as a means of fulfilling her longing.
However, Zhuang Qingning had no interest in pursuing why the hair was kept. She only wanted to return the wallet to the maid as soon as possible to finish the task Xiaowu had given her.
When Zhuang Qingsui heard Zhuang Qingning seemingly knowing the owner of the wallet, she immediately cheered up, "Then go return it quickly, the owner might be panicked now."
The wallet was a private personal item, exquisitely made and containing such private things, the owner must be worried indeed.
Zhuang Qingning nodded and asked Zhuang Qingsui to wait, "You stay here with the old lady, I will go give chase and see if I can catch up."
