2:00 PM.
Zhao Heng was busy when Li Haiyang from the oncology department walked in. He approached Zhao Heng's side, noticed he was busy, and didn't disturb him.
Zhao Heng realized someone was standing beside him and looked up to see it was Li Haiyang.
"Dr. Li? If you need something, just get a nurse to call me, why come yourself?"
Zhao Heng asked, somewhat puzzled.
"You're hard to get ahold of these days. If I hadn't come personally, I might not have been able to catch you."
Li Haiyang joked.
"Dr. Zhao, do you have some time this afternoon?"
After a pause, Li Haiyang asked again.
"Yes, what's up?"
Zhao Heng nodded.
"Here's the thing, there's a teaching session in the department about intraspinal analgesia for advanced cancer. It's attended by doctors from various local hospitals, and the director wants you to take this class."
Li Haiyang slowly explained.
"Teach a class? Me?"
