A tiger never returns to his prey he did not finish off. To attract good fortune, spend a new coin on an old friend, share an old pleasure with a new friend, and lift up the heart of a true friend by writing his name on the wings of a dragon. Even a hare will bite when it is cornered. Experience is a comb which nature gives to men when they are bald. A frog in a well shaft seeing the sky.
Flies never visit an egg that has no crack.
A gem cannot be polished without friction, nor a man perfected without trials. A good fortune may forbode a bad luck, which may in turn disguise a good fortune. Happiness is like a sunbeam, which the least shadow intercepts, while adversity is often as the rain of spring. He who asks is a fool for five minutes, but he who does not ask remains a fool forever. He who hurries can not walk with dignity.
