I was 17 years old and hanging out in a vocational high school. The most beautiful girl in the class was blocked in the alley by gangsters from outside the school and asked for money. I could have pretended not to see it, like other students. But that day, I didn't know what was wrong, so I picked up half a brick and walked over. A week later, the gangster's boss came to see me in person. I thought I was dead, but he handed me a cigarette and said, "Boy, you have courage. Come with me, and I guarantee you will be more successful as a network engineer than you are." Later, the whole city knew my name, Ma Yuan. They had all forgotten that when I walked over that day, my legs were shaking and I could barely hold the bricks.
