What is the relationship between MySQL default and whether it is empty

Rt
By the way, there's a blog.
If there is a default value, it is not allowed to be empty, otherwise it is inconsistent, the data is still the default value after modification
At the same time, I want to know if I set the default and then do not set a nullable query will automatically fill in the default if the settings can be empty what happens?
Of course I mean in strict mode

Please, somebody help me.

You don't want to try it yourself if you do it yourself. Some things will know the answer if you try it yourself.
