《资治通鉴·魏纪·魏纪五》
王昶为人恭谨忠厚，他给侄子起名王默、王沉，给儿子起名王浑、王深，写信告诫他们说： 我以这四字作为你们的名字，是要你们能顾名思义，不敢违犯。
昶为人谨厚，名其兄子曰默，曰沈，名其子曰浑，曰深，为书戒之曰： 吾以四者为名，欲使汝曹顾名思义，不敢违越也。
Wang Chang was a modest and honest man. He gave his nephews the names Wang Mo and Wang Chen, and his sons the names Wang Hun and Wang Shen. In a letter he wrote to admonish them, he said: I have given you these four names so that you will think about their meaning and not dare to act against them.
