A good book is a best friend who never turns his back upon us.
一本好书,莫逆之交。
A thousand friends are few, one enemy is too many.
朋友千人尚觉少,仇敌一人犹嫌多。
A true friend is known in the day of adversity.
疾风知劲草,患难见真情。
A true friend is one soul in two bodies.
真正的朋友好似两个身子长著一颗心。
A life without a friend is a life without a sun.
人生在世无朋友,犹如生活无太阳。
Be slow in choosing a friend; slower in changing.
选择朋友要审慎,摒弃更要审又慎。
