As a graduate student, I spent most of my working days in the lab, doing experiments, organizing documents, and finishing my thesis. After work in the morning, I will go to the gym with my friends. This activity is arranged before lunch and tends to increase our appetite. In the evening, it is time to play basketball and run, one of the two sports will be chosen. I spend some time with my guitar on weekends and weekdays, music and guitar are really happy springs on boring days, it is worth mentioning that I have been practicing Jay Chou's "East Wind Break" recently, it is a beautiful song.
