In December this year,the 4th Tianqin Cao Memorial Symposium on Protein Research will be held in Xiamen(Amoy).On this occasion,it is my pleasure to write a recollection in memory of Professor Tianqin Cao.It was rather late when I was able to study in Prof.Cao’s laboratory as a graduate student in the Institute of Biochemistry.After graduating from the Department of Chemical Engineering of Zhejiang University in 1948,I could not find a job in a chemical engineering factory;therefore,I changed my profession to biochemistry and worked as an assistant in the Department of Biochemistry of Hunan Yale Medical College.
