Git creates a new branch from a branch

1. Clone the code of the remote warehouse to the local

   git clone 
   

2. switch the branch to the one where you want to create a new branch

   git checkout 想要创建新分支的分支
   

3. Create a new branch on the current branch

   git checkout -b 新分支名称
   

4. Push local code to remote repository

   git push origin 新分支名称
   

5. At this point, a new branch has successfully appeared in the remote warehouse, and the local branch is also the branch just created.
