those have no kin and cannot support themselves

adopt new ways

tremble with fear

Change the leaf of Ke Yi

from of old till now(from time immemorial)

act stupidly

constant exchange of high officials' visits between two nations

Variety and harmony

beyond the ken of god or devil

be deeply concerned(be on tenterhooks)

sudden gain and loss respectively

swallowed a date whole(to do a thing without thought; to read without doing any thinking for oneself)

be too haughty to get along with others

set up wild shrieks and howls

humble views which may reflect lack of discernment

pull down one's vest

Be blind

get to the highest official position

sing while the stomach is as full as a drum

high-minded, lofty spirit, and pure action
