After Being Angered to Death by Her Children, the Feisty Old Lady Is Reborn in the 1980s

[Silver-haired literature + period setting + the 1980s + rebirth + family squabbles + building wealth + light ensemble cast]

When the fiery-tempered old woman Wang Cuihua falls seriously ill, her husband wants a divorce so he can marry again.

The children she raised with so much hardship won't contribute a single cent. They turn around and call someone else Mom.

Wang Cuihua can't catch her breath and literally dies of anger.

Reborn in the 1980s, Wang Cuihua spreads her hands, dumps her husband and children, and leaves the whole family in the lurch. She'll make her own money and spend it herself.

She carries a mobile phone, drives a Santana, and doesn't miss a penny of the money her children owe her for elder care.

But why is the man who used to be a teacher in his previous life now working as a gatekeeper?

And why are her clueless, unfilial children starting to seem so... lovable?
