Do you have any good friends? Who is your bosom friend? Who is your fair-weather friend? Who are your interested friends? Who is your lifelong friend? Who is your friend who you hate and love, but want to leave and can't bear to part with? A friend is a road, a lamp, a book, a sky and a river. A friend may also be a knife, a rope, a trap, a nightmare; I have all kinds of friends, but I can't express my affection and righteousness. Wealth is not a friend, but friends are priceless. Where are your friends when you need them most! Who is your friend when you are searching hard? This book will tell you all this!
