A friend is easier lost than found 得朋友难, 失朋友易。

　　A friend in need is a friend indeed. 患难见真情。

　　Between friends all is common. 朋友之间不分彼此。

　　Life without a friend is death. 没有朋友, 虽生犹死。

　　Misfortune tests the sincerity of friends. 患难见真情。

　　Old friends and old wines are best. 陈酒味醇, 老友情深。

　　A friend is never known till a man has need. 需要之时方知友。

　　A friend without faults will never be found. 没有十全十美的朋友。

　　He is a good friend that speaks well of us behind our backs. 背后说好话, 才是真朋友
