How often should you refactor- How often should you refactor?

problem ：

I had a discussion a few weeks back with some co-workers on refactoring, and I seem to be in a minority that believes "Refactor early, refactor often" is a good approach that keeps code from getting messy and unmaintainable. A few weeks ago, I had a refactoring discussion with some colleagues , I seem to be one of the few people who think “ Early refactoring , Often refactor ” It's a good way , Prevents code from becoming cluttered and unmaintainable .A number of other people thought that it just belongs in the maintenance phases of a project. Many others believe that it belongs only to the maintenance phase of the project .

If you have an opinion, please defend it. If you have any comments , Please defend .
