・Those who know, know.

例句
Since the cake I took as a souvenir was delicious and had a good reputation, I would like to say, " Those who know, know."
大家稱讚我帶回來的點心很好吃，所以我想說：「這是一家知者自知的店。」

"Those who know, know." 在英文中不像中文那麼常用，但在英文中也有這樣的表達方式 。
"Those who know,know well"可以表達為「知者自知」。此外，也可以表達為
"Those in the know, know."
