This book is written for you, for him, for all the "mindful" people, not for a few experts. Therefore, it focuses more on being interesting and abandons academic exposition. I would like to thank the Psychology Department of Beijing Normal University where I studied, thank my mentor Professor Lin Mengping from the Chinese University of Hong Kong, and thank my companions who have played these games with me - they have given me knowledge and courage, a wealth of materials and references. I also thank the outstanding creativity of Beijing October Literature and Art Publishing House, and my dedicated editorial colleagues, who have turned a good wish into a beautiful book.
Friends, let's play games together. I will share with you the sweetness and bitterness in this process, just as in the scorching sun of the desert we drink a handful of cool spring water together, and on the long journey we ride in the same car heading towards the distance.
