在写个小项目，简单说就是经过了阶段a，阶段b和阶段c，阶段c已经push到了远程库。
我现在在我的本地库把版本reset到了阶段b，现在我希望能重新push，覆盖并舍弃已有的阶段c，但是遭到了拒绝：
! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'git@github.com:qianjiahao/chatroom.git'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
现在该如何操作才能覆盖远程库的内容呢？
后来我就git pull，然后修改了后在push回去，不知道还有没有其他的解决方法。
