Nezha legend: Why is Nezha called the Ji Fa brothers?

Nezha legend Nezha is called Big Brother Ji Fa, because Ji Fa is very important to Nezha's growth. According to the query of iQiyi, Ji Fa, the son of Ji Chang in The Legend of Nezha, helped people all over the world to resist tyranny, abolish Zhou Wang, rebuild the world and restore peace. He was born into a noble family and was imprisoned as a slave by Zhou Wang in Chao Ge. His life is always in danger, but he is always strong and unyielding. His perseverance and steady personality have greatly influenced the growth of Nezha, and he is a good example for Nezha to learn. So Nezha was called the Ji Fa Brothers.
