烈酒烧喉情话烫嘴
[liè jiŭ shāo hóu qíng huà tàng zuĭ]
'Liejiao Shaohou Qinghua Shuangzui', translated as 'strong alcohol burns the throat and sweet words scald the mouth', conveys the strong feeling and complexity of love-related experiences, such as how both affectionate moments (symbolized by sweet words) can stir powerful emotions (like a burn).
