compare & pull request (compare and submit) the reason for the occurrence of the run git push origin branch name

The code of the local warehouse will be pushed into the remote warehouse. From Repostitory to Remote, the
remote warehouse needs compare & pull request (compare and submit) to merge

Here I have no problem with the branch dev push, just click this green command to enter

There is no commit to write for master submission, because who can the master submit to, so as a beginner, I was confused for a while! ! ! ! !

If it is submitted by the dev branch,
you can see the New pull request button, the same green and oily~~~~
