My brother was the 1st generation Phd in medical field in China after 文化大革命. My sister-in-law did not even graduate from high school during 文化大革命 since she was a professional swim player (省遊泳隊). She also got a Master in China.
Right now, both of them are MD (醫生) in USA and have their own clinic.
I just want to say some 工農兵學員 are very good.
