square outside and round inside

be selfless and fearless

Go on a wild goose chase

tyrannically abuse one's power

without a doubt(be beyond any shadow of doubt)

grasping valuables in one's hands and carrying gems in one's bosom

(of stature) short and strong(short and sturdy)

hoodwink those above and bully those below

at/on a snail's pace

All is quiet and still.

disappear into thin air(spread like wildfire)

with both military and civil ability

have a bumper harvest

using broken jars for windows and ropes for door hinge

sovereign remedy(remedy for all things)

be simmering with rage

get wind of the matter and escape(run away upon hearing the news)

without dispute(inarguable)

get within a little distance of somebody

say one's piece(say out one's say)
