Abstract: When I received a phone call from President ZHANG Xi of Jilin University inviting me to write an article for Echoes and Reflection on Graduate Education, Jilin University, I gladly agreed. After a day of contemplation, I realized that what I knew best and remembered most deeply was the education and guidance, which was received at the Department of Chemistry at Jilin University, particularly from my mentor Professor TANG Au-chin. It was under his nurturing that a young man born in Lianhua Nigou Village, Shulan County, Jilin Province, set off on a long and persistent journey in pursuit of science. Many memories began to resurface.
