Back in college, the most popular job position was product manager. Many of my friends became product managers at various companies. At that time, I was couch-surfing in Shanghai, living in a 10-square-meter room. It was tough, and we often did laundry there. The guy next door fell in love with me at first sight. The rent was about 800 yuan a month. Youth was my good friend, and we were quite happy. Later, we traveled to many places, took lots of photos, and posted them on QQ Zone.
