git - New branch pull request problem

Question

My main branch is called wholesale/master
I created a new branch btn yesterday. The changed code is in file a and submitted. There is no merge
If I want to change a today file, then should I submit on the basis of the btn branch or the wholesale/master branch? So who should we compare with when making a pull request?

Answer 1

Just continue branching in btn分支上工作，等感到工作告一个段落之后，合并到主干就行。
如果是自己的库的话，直接merge再push就可以。如果是别人的库，选择compare across forks，比较别人的主干和自己的btn.

Answer 2

Local btn分支上工作，修改完毕之后push到远程的btn分支上。
merge remains the same.
