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

Before starting a new business, he said, 'Nothing ventured, nothing gained.'

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 cautioned not to speak ill of others, saying, 'Illness enters by the mouth, and disaster does not come out of it.'
