So Zheng Peng didn't hold back, looking at the menu and ordering a few expensive dishes. After all, Sun Xingyao is much wealthier than him. The cost of this meal is probably just a fraction of Sun's income; as a department head, his salary is much higher than that of a regular doctor.
Moreover, in his spare time, he could take on extra work here and there. As long as a doctor wants to make money, there are numerous ways, like accepting red envelopes from patients, which has become an unspoken rule, or reselling medical equipment for kickbacks, which makes much more than a doctor's salary. Sun Xingyao must have made quite a sum in these ways over the years.
Zheng Peng speculated quietly, and then he ordered a pricey bottle of liquor, saying, "Since Director Sun is treating us, I won't be polite. Plus, how can we catch up without some drinks?"
