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。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。Between friends all is common. 朋友之间不分彼此。He is a good friend that speaks well of us behind our backs. 背后说好话，才是真朋友。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。...
