玻璃易碎人心可畏
[bō lí yì suì rén xīn kĕ wèi]
'Glass is fragile and the heart of man is awe-inspiring' refers to two interrelated aspects: first is about how easily delicate things can be destroyed; the other part speaks about people's hearts, which can sometimes possess a power that's both admirable and scary, hinting the complexity of human emotions or intentions.
