Strike terror in one's heart

come to naught(go up in smoke; turn to dust and ashes)

Unexpected disaster

lying at sixes and sevens

young greenhorns

talk at random

what has been spoken

boast

A noble spirit will never perish.

Make friends with congenial persons

begin well and end well

Be suddenly enlightened

intrusive(officious)

nip to the bone

guard the state and cherish the people

treading on tiger's tail or walking on the ice in springtime

an ass in a lion's skin

countless like the sand of the Ganges

Fox running around

recover one's original simplicity(regain nature)
