Xu Xiangbei received a call from Dean Sun of Earth Sea First Hospital during dinner: "Advisor Xu, hello, I'm calling about the lecture at our medical school. Are you free this weekend?"
With Dean Sun's reminder, Xu Xiangbei recalled that he had promised to make time one weekend to give a lecture to the students at the Herbal Medicine School.
He chuckled: "Dean Sun, I'm just a junior advisor, probably around the same age as the students at the Herbal Medicine School. Is it appropriate for me to go?"
