待价而沽 — “To wait for a good price before selling”

During the Spring and Autumn period, Confucius traveled with his disciples to various states to advocate his political ideas. Although no one accepted or appointed him to an important position, he did not lose heart.

His disciple, Zigong, asked Confucius what he would do if he obtained a beautiful jade. Confucius replied without hesitation, “Sell it, sell it! I am waiting for someone who knows its true value to appear.”
