git reflog // 即reference log 可以参考的log

 a "detached head" state refers to a situation where you are no longer on a branch, but instead you are directly pointing to a specific commit.
when you are in a detached head state, any changes you make will not be associated with a branch, and if you create a new commit, it will not be part of any branch.

# your branch is ahead of 'origin/<branch_name>' by 2 commits.
#   (use "git push" to publish your local commits)

git log origin/<branch_name>..<branch_name>
