"Doctor Ling, we are about to organize the Asia-Pacific Region's Study of Hepatology Congress and would like to know if you could do us the honor to join us and perform a surgical demonstration." Gao Meng took the opportunity of the afternoon break to approach Ling Ran and invited him in a respectful tone.
When a person did something, he should do it with 90% sincerity for work's sake, and the other 10% was just for show.
Gao Meng knew intellectuals' bad habits. Hence, even if it was just drinking, he had to be respectful of them. He was afraid that people would be unhappy, and the two crates of good wine he brought will go to waste.
He had to be even more respectful for today's invitation.
