风丝一寸柔肠
[fēng sī yī cùn róu cháng]
The phrase 'A thread of wind, an inch of tender intestines,' vividly depicts the scene where gentle breezes evoke a sense of longing and nostalgia. It's often used metaphorically to express soft affection, subtle worry, and melancholy, resonating with feelings of delicate love, longing, or homesickness.
