"Guo Yi, you actually understand medicine?" Wang Qiaolin asked.
"A little bit!" Guo Yi said.
"You don't look like someone who knows just a little!" Wang Qiaolin giggled, then said, "In this world, there aren't many who master the art of acupuncture. My grandfather once told me there are different schools of acupuncture. But your technique must be special, right? May I know which school you are from?"
"My master is like a dragon: you can see its tail but not its head," Guo Yi shook his head.
"Oh!" Wang Qiaolin nodded.
After two hours of flying, the airplane finally landed in Hong Kong.
"Mr. Guo, we owe you so much for this time!" the old man personally thanked him, saying, "If Mr. Guo has time, I would like to invite you for a meal."
"No need!" Guo Yi waved his hand, "Saving people is a doctor's duty. You don't have to be so polite!"
"This…" the old man hesitated for a moment.
Without waiting for the old man to speak, Guo Yi strode away.
Wang Qiaolin followed closely behind.
