In prosperity, our friends know us; in adversity（危难时）, we know our friends.
A friend is a gift, whose worth cannot be measured except by heart.
A faithful friend is beyond price, and there is no weighing of his goodness.
The most cherished（珍惜） thing in life is friendship. The most precious thing between us is understanding.
The language of friendship is not words but meanings.
Friendship brings beauty to our days joys to our world.
Cease to struggle and you cease to live.
Great works are performed not by strength but by perseverance（坚定不移)
