A broken friendship may be soldered，but will never be sound.破裂了的友谊，再补也难如故。A brother is a friend given by God.兄弟是天赐的朋友。A friend in need is a friend indeed.患难见真情。A friend is easier lost than found.朋友易失不易得。A friend is known in necessity.患难见友情。A friend to all is a friend to none.对一切人都是朋友，对哪一个也不是朋友。A friends frown is better than a fools smile.朋友对你皱眉，胜过傻瓜对你微笑。
