话说江南小镇上，住着两个年轻人，一个叫阿福，一个叫阿寿。他们虽然家境悬殊，阿福家境殷实，阿寿家境贫寒，但两人志趣相投，自小一起长大，一起读书习武，患难与共。在一次山洪暴发中，阿寿被困山谷，阿福不顾个人安危，奋不顾身地跳入水中，将阿寿救出。从此以后，两人更是亲密无间，常常以兄弟相称，称兄道弟，一起闯荡江湖，扶危济困，行侠仗义，成为远近闻名的侠客。他们的故事，在小镇上广为流传，成为一段佳话。
Once upon a time, in a small town in southern China, there lived two young men, one named A Fu and the other A Shou. Although their family circumstances were very different - A Fu's family was wealthy, A Shou's family was poor - the two shared the same interests and grew up together. They studied and trained together and overcame difficulties together. In a devastating flood, A Shou was trapped in a valley. A Fu, without regard for his own safety, jumped into the water and rescued A Shou. From then on, they were even closer and called each other brothers, "chengxiong daodi". Together they traveled the country, helping those in need, being brave and courageous, and becoming well-known heroes. Their story became widely spread in the town and became a legend.
