After more than a year, the book was finally completed. Over the past year, there were hesitations, some hesitations, and even thought of giving up, but in the end they persisted. No matter what, thanks for their support for Xiao Wu for their brothers and sisters over the past year, especially for their encouragement to Xiao Wu, "Oil Drop Drops of Drops" and "Mo Bai" for their always encouragement. Of course, I also have to thank "Listen to the Rain at Night" and "The Two" for their rewards.
It is your encouragement that has made this book come to this day and Xiaowu persisted to this day. Thank you! No matter how good the grades are, with everyone’s support, Xiaowu will definitely work harder and constantly enrich himself, and strive to make everyone more satisfied one day!
