My brother was obsessed with gambling and stole and lost all the 20,000 yuan I had saved for tuition. But my mother defended my brother and accused me: "This house will belong to your brother in the future. Why did it cost you 20,000 yuan? You will still have to pay for your brother's betrothal gift in the future." I went crazy with anger and hacked at my brother's room with a kitchen knife, hacking all his treasures to pieces. When leaving home, my brother threatened: "Zheng Yang, I will kill you!"
