说爱太烫嘴谈亲太伤身
[shuō ài tài tàng zuĭ tán qīn tài shāng shēn]
'Speaking of Love Scalds the Lips, Talking Intimacy Hurts the Body,' this expresses a view on how discussing love directly can make someone uncomfortable ('scald the lips'), and getting too close into someone else's private matters (talking too much about intimacy) could cause trouble or pain ('hurt the body'). It suggests that talking overtly about certain things may lead to unforeseen problems.
