question 1:

take the remote branch and break up a new branch, which means pulling the branch of the remote remote version library origin locally.

git checkout -b local-my-branch origin/my-branchcheckoutlocal-my-branch

question 2:

first of all, you need to figure out what each parameter represents git push .

$ git push <> <>:<>

git push origin: mybranch : means that an empty local branch is pushed to a remote mybranch branch, which is equivalent to deleting a remote mybranch branch.

$ git push origin :mybranch
-sharp 
$ git push origin --delete mybranch
