Can it be used instead of doing with good doing? Why?

No, it's all fixed.

To do is mainly used to indicate a one-time concreteness that will happen sexually. Its logical subject is implicitly referential. Doing is mainly used to denote recurring, habitual, and abstract behaviors. Its logical subject is implicitly implicit.

1.Infinitive.

Being the subject often indicates a specific action; Gerunds are often used when denoting general or general abstract concepts.

For example: walking is a good form of exercise for both young and old

2.After "there it +be+ no use(good help need)" is often used as the subject of gerunds, and infinitives are rarely used, such as:

it/there is no use crying over the split milk.

it/there is no help taking this medicine.

However, if the logical subject of the infinitive is used in the sentence pattern, only the infinitive can be used, such as:

there is no good for us to do that exercise.

3.The infinitive can be used in conjunction with when, where, how, what, whether, etc., to be the subject, object and predicate in a sentence.

Gerunds cannot, e.g., how to solve the problem is a hot potato

to do, a one-time action. Doing regular behavior.

The infinitive as the subject generally refers to a specific action, while the gerund as the subject mostly refers to the general. For example, learning is necessary for all of us in this society.

Hello! What you are giving is a fixed sentence pattern in which it is the subject of the form. Their basic structure is-

it is no use good doing sth

The meaning of the sentence pattern is - what is useless and beneficial to the sedan fierce. For example – it's no use crying over spilt milk.

Mu has sailed into a boat, and regret is useless.

This is a sentence pattern in English.

It is a preamble that is used as a formal subject.

is a predicate.

No use and no good are expressions, and good is a completely negative expression. it is ..They form the main system table structure.

doing is a gerund, and it leads to the phrase that is the actual subject.

The meaning of the whole sentence is: what to do is (totally) useless, and what to do is (completely) bad.

it is no use doing what is a search for imitation is useless.

It is no good doing.

The above is a fixed sentence pattern.

It is the formal subject, and the real subject is doing.

For example: it is no good reading the book

There is no benefit in reading the book of the Preparatory Calendar.

it is no use crying over the spilt milk.

It is difficult to recover when covered with water, and it is useless to regret it.

These two sentence structures are the main table structure, in which the state is the formal subject, the book answer is the verb, no yours or no good is the expression, and doing or doing something is the real main language, for example: it is no use quarreling with your parents it is no good staying up late.

Because this in order to avoid being top-heavy, it is equivalent to using Chang Hui Zen in an "inverted" form, which is equivalent to "xx is not good". If you look at the world in this way, the dust-resistant part of "xx" must be a noun, then the corresponding must be the noun form of the verb, in other words, the form of "+ing".

This sentence structure can be seen as a nominative table structure, where it is the formal subject, and the following doing-led gerund phrase is the actual subject.

Both sentence patterns are in the form of ing.
