姚奠中先生是我的导师。自从上个世纪八十年代初成为先生的研究生以后,近三十年来每次进入姚先生的书房,看见先生慈祥的笑容和睿智的目光,便有一种如沐春风的感觉。作为学生到先生的书房,大多是向先生请教、解决疑难问题。而在姚先生的书房里和先生聊天,却还是一种高水平的享受。 Mr. Yao Dianzhong is my mentor. Since he became a graduate student in the early 1980s, every time he entered Mr. Yao’s study in the past three decades, he saw a gentle smile and a wise eye. As a student to Mr.’s study, mostly to ask for help to solve difficult problems. In Mr. Yao’s study and Mr. chat, but still a high level of enjoyment.
