The Bullied Martial Arts Legend

A child was bullied since he was a child. He came from a very difficult family. His parents were bullied. He himself was often beaten and scolded when he was a child. Teenagers can learn kung fu from a teacher and practice hard. When they grow up, they still can't beat others in kung fu. Others have strong kung fu, so they learn from a teacher and study kung fu hard. Finally, they can get revenge, and finally live in seclusion in the mountains. From now on, they will not care about trivial matters in the world, and spend their old age peacefully!
