The code in the book has advantages, but I don't feel that there is much difference, so I no longer use the intermediary mode to write code here. State mode is an unusually excellent mode, which may be the best way to solve some requirement scenarios. Although the state mode is not a simple to clear mode (it often brings about an increase in the amount of code), once you understand the essence of the state mode, you will certainly thank it for its incomparable benefits in the future.

This article describes the state mode in detail韩信被尹旭派出去……暂时的借给刘邦了。
