Leng Bing looked it up and saw it was true. He couldn't help but get excited. "Brother-in-law, you really are a doctor!"
"Now you believe me," Jiang Xinghai said, taking a drag from his cigarette.
"Brother-in-law, you and my sister should get some rest too. I'm off to bed," Leng Bing said, tossing his cigarette butt and turning to leave.
"Remember, don't get too carried away."
Jiang Xinghai reminded him again, "And if your wife isn't feeling well, you should just be the milkman, understand?"
"Brother-in-law, what do you mean, 'the milkman'?" Leng Bing asked, confused.
"It means exactly what it sounds like."
Jiang Xinghai didn't want to explain it too clearly, but Leng Bing seemed hung up on it, so he had to elaborate a bit. "Think about it. Doesn't a milkman just deliver fresh milk to the doorstep?"
"Yeah," Leng Bing agreed.
"Exactly. The milkman just delivers to the door, leaves the milk, and goes," Jiang Xinghai said with a knowing look.
