Reborn in the 80s and Remarrying an Officer, Let the Ungrateful Cry!

In her past life, the old lady poured her heart and soul into raising three children, but it turned out every one of them was an ungrateful wretch.
They kicked her out of the house when she was old and useless.
Starving, freezing, and sick, she died under a bridge culvert.
Suddenly, she was reborn back in the 1980s.

When that scumbag, who would later remarry his "white moonlight" ex-wife after her death, swam towards her.
She decisively saved herself.
She would never again marry this man who had ruined her life.
As for those three ungrateful wretches he had with his ex-wife.
They can all get lost!
She took back her own university acceptance letter.
She took down the scumbag man and the bitchy woman.

Looking at the three wailing, hungry children.
The old lady felt that in this life, instead of trying to provoke them, she might as well improve herself.
