Unite in a concerted effort

Know everything you want to know

Associate oneself with undesirable elements

burst forth suddenly whisk one's sleeves and depart

Head collar

an undeserved gain

a copper clepsydra

Introduction

shape without soul

the iron tree bursting into blossom(something hardly possible)

One's head is spinning.

God's justice never fails.

The rabbit is in short supply.

as fast as the hare runs and as swift as the wild duck starts flying

have a dizzy spell(be out on one's feet)

one's eagerness to look for worthies and virtuous officials

Hide one's capacities and bide one's time

see stars(feel faint and vision blurred)

The revered man is dead.

The world is in a turmoil.
