1、找到要上传的项目的目录，右键打开命令行工具

2、新建一个本地分支，必须保证分支名称与远程的分支名称相同

zhai@DESKTOP-R14D2UH MINGW64 /d/github/git-test (dev)
$ git branch dev-demo

zhai@DESKTOP-R14D2UH MINGW64 /d/github/git-test (dev)
$ git branch
* dev
  dev-demo
  master

切换到新建的分支：

$ git checkout  dev-demo
Switched to branch 'dev-demo'

zhai@DESKTOP-R14D2UH MINGW64 /d/github/git-test (dev-demo)

3、为远程地址创建别名

zhai@DESKTOP-R14D2UH MINGW64 /d/github/git-test (dev-demo)
$ git remote add test https://gitee.com/zhai_huabing/git-test.git

zhai@DESKTOP-R14D2UH MINGW64 /d/github/git-test (dev-demo)
$ git remote -v
my-picture      https://gitee.com/zhai_huabing/my-picture.git (fetch)
my-picture      https://gitee.com/zhai_huabing/my-picture.git (push)
origin  https://gitee.com/zhai_huabing/jpa.git (fetch)
origin  https://gitee.com/zhai_huabing/jpa.git (push)
test    https://gitee.com/zhai_huabing/git-test.git (fetch)
test    https://gitee.com/zhai_huabing/git-test.git (push)

4、pull

zhai@DESKTOP-R14D2UH MINGW64 /d/github/git-test (dev-demo)
$ git pull test dev-demo --allow-unrelated-histories
From https://gitee.com/zhai_huabing/git-test
