"Tangyu, can you wait a moment?" Bi Wanting hurried after him.
Tangyu stopped and asked, "What is it?"
Bi Wanting said, "Thank you for diagnosing my grandfather's illness, and thank you for treating him. I don't know if you are free this noon, but I would like to invite you for a meal and ask about my grandfather's condition. Would you do me the honor, Captain Tang?"
Tangyu smiled and said, "You're overstating it, you've already thanked me. It's too polite to ask me for a meal, there's nothing much to discuss about your grandfather's condition at the moment, and I have some things to take care of at noon, so I'm sorry."
