"I'm afraid that if you see the money, you'll think I'm bribing you, and then take back the opportunity you gave me. I'll give it to you later."
"Money?" Professor Liu did not expect that there was really money in there.
"Yes, last night Wang Yafei came to me, saying he wanted to pay the treatment fee. I think this money is a recognition of our work, so I should accept it. But since I don't have a license now, it would be the same as practicing medicine without a license, so I wanted to give it to you."
So that's what happened. Professor Liu nodded, took the envelope, and opened it only to frown again.
"Why are you taking so much from him?!"
"...You think this is too much? No wonder you've been researching for a lifetime and still live in a barracks-style building."
"I have a house, I just sold it — return most of this money, leave some for your senior brothers and sisters as research funds, and this is for you."
