君子之心事,天青日白,不可使人不知;君子之才华,玉韫珠藏,不可使人易知。
君子的心事,要像青天白日那样光明磊落,不可对人有所隐瞒。
君子的才华,要像珠宝玉器那样深藏不露,不可让人轻易得见。
The heart of a worthy man should be as clear as the blue sky and the bright sunshine, so that everybody can lightly feel it. But on the contrary, his talents should be carefully concealed like jade and pearls, so that nobody can easily find them out.
