The young master in the dormitory offered a reward of 8,000 yuan for someone to run physical education classes. As a not-so-rich person, I immediately accepted the offer. However, my brother kept obstructing me and even tried to make me quit. He instilled in me that children from poor families should have some backbone, but I didn't have any backbone when I used my own labor to make money. Others were also resistant to my brother's preaching.
