The Inheritance Test

A 70-year-old woman's only home is about to be demolished. After her children learn the news, they change their attitudes and take turns visiting to show their filial piety. The woman sees this, but she knows in her heart that it's likely related to the demolition compensation. To secure a truly peaceful and happy old age, she decides to quietly test them to see if their filial piety is sincere or just a ploy to fight for the compensation.
