88 hoursIn this book, the one-and-a-half hour number is selected from the textbook "Haemong house" that adults used to teach their children. This book means to awaken foolishness, and it was a family textbook for children and adolescents growing up. This is because of the idea of making a book known to more people, the taste and style of a city, and the lesson to be learned. I hope that the growing generation will have another window to meet with the world through this city.
