What are the idioms that mean "each shows his ability"

Like the Eight Immortals crossing the ocean, each shows his magical powers-proving his value by his own resources; Faced with the same difficulties, everyone gave full play to their talents.

Interpretation metaphor has its own way of doing things. It is also a metaphor to compete with each other with their own skills.

When the Eight Immortals crossed the sea, they all showed their abilities.

Source Wu Ming Cheng En's eighty-first journey to the West: "It was the Eight Immortals who crossed the ocean and showed their magical powers alone."

I am separated from my brother now. These brothers are the Eight Immortals who traveled across the ocean, showing their magical power. I showed my brother my life. (Qing Lvyuan Li's "Qi Lu Deng" back to 68)
