Definitions (粵典–words.hk)

語句
一句廣東話歇後語，下句係「淒涼」；字面意思係老公幫老婆撥扇，噉老婆（即係妻子）就會好涼爽，而「妻」同「淒」係同音嘅，所以就係「淒涼」；一對嘅仲有「老婆擔遮」
an expression meaning miserable and wretched, literally "the husband fans", a pun based on the link with 妻涼 (cai1 loeng4, "wife feels cool", i.e. as a result of the husbands fanning) which sounds the same as 淒涼 ("miserable")
