说爱太烫嘴谈情太伤身
        
            [shuō ài tài tàng zuĭ tán qíng tài shāng shēn]
        
        
            'Speaking about love burns one's mouth and talking about affection harms one's body.' This signifies the dangers or potential harm in expressing strong romantic feelings; conveying fear or hesitation about showing or discussing love due to past pain.
