He is the type of person who understands ten from hearing one.

After many years of effort, he was finally able to achieve his goal and make a name for himself.

He said, 'A nameless star comes out in the evening,' teaching me that achieving a goal is not easy.

He is exactly in the state of 'A frog in a well does not know the vast ocean.'

He spoke of his big dreams, saying, 'How can a sparrow understand the ambitions of a swan?'

He was able to achieve career success and fame after much hardship.
