wow~!
I have got a new skill~ ,create a new empty branch.
Steps are as follows:
Step 1:
Create and switch a new branch.
git branch <new_branch>
git checkout <new_branch>
git rm --cached -r .
git clean -f -d
Step 2:
Create an empty commit.
git commit --allow-empty -m "[empty] initial commit"
Step 3:
Push the new branch.
git push origin <new_branch>
