"It's better than nothing that I can get temporary relief. I also had a belly ache two days ago. It was very uncomfortable that I couldn't even sit still!" said Professor Lu with a smile.
"I see, I'll give you some herbs to try. How long are you going to stay here?" asked Wang Yao.
"Three days," said Professor Lu.
"I see. I'll think about it and will deliver the herbal decoction to you after I get it ready," said Wang Yao.
"You don't need to deliver it. Call me once the decoction is ready. I'll get someone to fetch it," said Tian Yuantu.
"Okay," said Wang Yao.
Tian Yuantu stopped Wang Yao when he was ready to leave.
"How about having lunch together here?" suggested Tian Yuantu.
"Thank you, but I've got errands to run. Shall we catch up on another day?" said Wang Yao.
"Okay, Professor Lu, could you please wait for me for a moment? I'm walking Yao out," said Tian Yuantu to Professor Lu.
