In 2009, Sean Chambers published a series of articles on his blog 31 Days of Refactoring: Useful refactoring techniques you have to know , one article a day, introducing a method of refactoring, and 31 articles in a row, hence the name "Refactoring Three" Eleven Days: Refactoring Tools You Should Master". In addition, Sean Chambers organized these 31 articles [that is, 31 reconstruction methods] into an e-book. The following are the original blog link and e-book download address:
