Introduction

This book is based on the idea behind the saying "prevention is better than cure." If all parents give their children (especially those ten to fifteen years old) good moral and practical knowledge, they will help them become good people for the rest of their lives.

If parents can’t teach these things to their children in time, they can’t prevent these young people from developing criminal habits. Throughout this book, I try to warn preteens and young teenagers not to start bad habits.
