have overt and covert contacts

sharpen one's sword and oil one's gun

Be carried away into a region of dreams

be all at sea(can not take it in)

fling a gleaming pearl into darkness

Indulge in the wildest fantasy

leaving without a trace

be completely bewildered

without any complaint to end of one's life

People are healthy and things are plentiful.

flirt(play the coquette)

be stuck for

betray friends for personal gain(sell friends to obtain a promotion)

shed crocodile tears

The people are poverty-stricken and national treasury is exhausted.

be all eyes(with all the eyes in one's head)

the name matches the reality

Buy cheap and sell expensive

be in the shade of obscurity all one's life

cut a brilliant figure(above the average)
