A life without a friend is a life without a sun. A father is a treasure, a brother is a comfort, but a friend is both. A friend in court is better than a penny in purse. A friend is a second self. We can live without a brother, but not without a friend.
人生在世无朋友,犹如生活无太阳。
父亲是财富,兄弟是安慰,朋友兼而有之。
囊中有钱,不如朝中有友。
朋友是另一个我。
我们生活中可以没有兄弟,但不能没有朋友。
