No doing and not doing

“。 . . +the habit of no smoking "I don't understand what you mean. . . It can only be said that it is incorrect.

not can't be changed to no casually.

the form of p>No+verb ing is only used in some warning signs, slogans, notices and other places, and its expression tone is very strong. And it can only be said alone, not in sentences.

For example,

no smoking.

no parking.

no food or drink in the lab.

And not is used in general declarative sentences to express negation. For example, you can use not, which means "the habit of not smoking" (but in fact, pure English does not use this method when expressing this meaning).

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

I don't understand why you have to use this expression. The sentence you added means "I have the habit of prohibiting smoking", which is a very strange sentence in Chinese. Or where did you get this sentence? However, I think it is awkward to say this in any context. Still use not.
