Wu Hongfei is a good mentor; it is thanks to his selfless teaching that Wu Kun, Sun Hai, and Bai Qingqing have made rapid progress in their medical skills.
The order goes from oldest to youngest, starting with Wu Kun. After Wu Kun shares his opinions on the medical cases, it proceeds to Sun Hai, followed by Wu Zongyu, and then Bai Qingqing. After they express their views, Wu Hongfei would point out any inconsistencies in their understanding, which meant that a meal could take several hours to finish.
Lan Tian doesn't like this serious atmosphere and doesn't like to talk about official matters during meals. Eating for her is just a formality; she only tasted some of the Spiritual Vegetables she brought, without touching the other dishes. Mo Junhua developed the habit of eating quickly back in the military; despite slowing down to match the pace of everyone else, he still finished too fast.
