・experts know best
・every man to his trade

「術業有專攻」的英語用 experts know best 或是 every man to his trade 來表達。

Are you going to buy here? The experts know best, so you should buy it at a specialty store.
（你打算在這裡買嗎？術業有專攻，最好在專賣店買比較好。）
※ specialty store（專賣店）

People say, every man to his trade, right? So regarding to 〇〇, you should leave it to him.
（正所謂，術業有專攻，所以〇〇的事情還是交給他吧。）
