git to delete the branch and fall back to a previous version submitted

1.git create and delete branches:

　　Created: git branch branch name

　　Local delete: git branch -D branch name

　　Remote delete: git push origin: branch name

2.git fall back to the version submitted previously

　　git log: View logs submitted

　　git reset --hard commit_id(这个是提交的id,可以通过上面的命令查看要回退的那个提交版本的id,或者直接到git的网站上面看分支的提交记录，里面也可以获取到你要回退的那个提交的id):本地仓库回退，不影响远程，有需要再自己push
