This proverb uses the image of the white egret, known for its purity and proud demeanor, to discourage people from being overly proud or vain in public. It emphasizes the importance of remaining humble and modest, even if we possess qualities or assets that could make us proud. Essentially, it cautions against boasting or showing off one’s achievements in front of others. An equivalent proverb in English would be ‘Clothes do not make the man.’
