How does yevgeny finally get through to seryozha getting a promise from his son that he will no longer smoke support answer with textual evidence

By telling him a bedtime story of a kingdom where a young prince died due to consumption and left his old father to be killed by enemies.

Explanation:

In Anton Chekov's short story "Home", the third person narration tells the story of a prosecutor trying to teach his seven year old son about the bad habit of smoking.

Yevgeny Petrovitch Bykovsky, the father of the young boy Seryozha had been told by the governess that his son had been caught smoking, twice. It was his attempts to teach his son the bad influence of smoking that the whole plot is concerned about. Initially, he tried to tell him like a normal lecture but the young boy paid no interest in his speech. Rather, he was dwelling in his own world.

Then, right before bedtime, the boy requested his father to tell him a story. It was then that he began telling him of an old king and his young son who "smokes". He then went on to narrate that the son "fell ill with consumption through smoking, and died when he was twenty. His infirm and sick old father was left without anyone to help him. There was no one to govern the kingdom and defend the palace. Enemies came, killed the old man, and destroyed the palace..." At this, Seryozha promised that he was "not going to smoke any more. . . ." In this way, Yevgeny finally got through to his son about not smoking again.
