说爱烫嘴谈爱烫舌
[shuō ài tàng zuĭ tán ài tàng shé]
'Shuo Ai Tang Zhui Tan Ai Tang She', means talking about love burns one’s mouth and discussing it burns the tongue, reflecting an understanding of the potentially bitter-sweet nature of love and how words in matters of love are always painful or awkward sometimes.
