cheate a new branch and switch to it:

$ git checkout -b branch-name

---

replace local branch with server branch:

$ git reset --hard HEAD~3         # HEAD~3 means rollback 3 commit versions

if you make a mistake when using: git reset --hard , then the commits before it would lose(see git log), how to recover them ?

$ git reflog
$ git reset --hard  <sha>
