git push -u origin master
# The above command pushes the local master branch to the remote origin, and -u sets the default remote branch as origin. After this, you can use `git push` without any arguments.

# Push all local branches to origin
git push -u origin --all  

# If development is based on the local `case_dev_wanzi` branch, push it to the remote `case_dev` branch
git push origin case_dev_wanzi:case_dev
