Měi ge hángyè de gāoshǒu dōu yǒu zìjǐ de kān jiā běn lǐng.
Every master in their field has their own signature skill.
Tips
memory
Literally 'the skill that guards the house (看家)' — the one technique a master keeps in reserve for when it really counts. Think of a chef's signature dish or a band's encore.
mistakes
看 here is kān (1st tone, 'to guard/watch over'), NOT kàn (4th tone, 'to look at'). 看家 = 'look after the house'.
