語句
一句廣東話歇後語，下句係「陰功」；老婆幫老公擔遮，畀老公遮陰，就係「陰公」，「公」同「功」同音，就變成「陰功」；一對嘅仲有「老公撥扇」 an expression meaning sad and pitiful, literally "the wife holds the umbrella", a pun based on the link with 陰公 (jam1 gung1, "to shade the husband", i.e. by holding the umbrella to block the sunlight) which sounds the same as 陰功 ("pitiful")
