Long ago, in a bustling market, a young scholar was hurrying home. Suddenly, he saw a strong bully bullying a weak vendor. The bully not only robbed the vendor of his goods but also beat him up. The scholar, filled with righteous anger, drew his sword, shouted loudly, and rushed forward to fight the bully. Although the bully was strong, he couldn’t stand up to the scholar’s sharp swordsmanship and finally ran away in disgrace. The vendor was grateful and thanked the scholar repeatedly. The scholar waved his hand and said, "When you see injustice, you help with your sword, this is the responsibility of every scholar." From then on, the scholar’s heroic deed spread far and wide, and people praised him for his courage and justice.
