大言不慚、夸夸其談fanfaronade rodomontade
大義凜然inspiring awe by upholding justice
大義滅親place righteousness above family loyalty
大智若愚Still waters run deep. An empty vessel makes the most sound Still water runs deep
呆若木雞dumbstruck transfixed
待人接物the ways one gets along with others
殫思極慮rack one's brains
膽小如鼠cannot say boh to a goose
膽戰(zhàn)心驚的funky
淡泊明志not seek fame and wealth
道貌岸然be sanctimonious
得過且過drift along muddle along
