Look at a netizen who observed an absolutely mind-blowing pattern:

When a child is born, they’re immediately left in their hometown to be taken care of by their grandparents.
The couple goes out to work, and only occasionally comes back for the New Year to buy a few cheap clothes and a few snack gift packs.
When the child grows up, by then the grandparents are often weak and sickly.
Then they tell the child: “You were taken care of by your grandparents since you were little. You have to take care of your grandparents—you need to pay for your grandparents’ medical treatment and living expenses.”
They manage to escape both the responsibility of raising a young child and the obligation to support aging parents………
