Metaphor has its own way of doing things. It's also a metaphor for competing with each other with their own skills.

Legend has it that eight Taoist immortals went to the flat peach party of the Queen Mother. They came to the East China Sea. Lv Dongbin suggested crossing the sea separately, Tie Guai Li stood on the Long Touzhang, Han Xiangzi sat in the flower blue, and Lv Dongbin, Lan Caihe, Zhang Guolao, Han Zhongli, He Xiangu and Uncle Cao crossed the sea by their own flutes, paper donkeys, clappers, drums, bamboo covers and jade plates.

Now I am separated from my younger brother. These brothers are eight immortals crossing the sea, each showing his magical powers.

I asked my younger brother to look at my life. (Qing Lvyuan Li's "Qi Lu Deng" back to 68)
