Later, I figured it out. Zhao Juan's parents actually wanted a boy after having her, but they were too old at that time and their bodies couldn't handle it.

So they bought a boy instead.

However, not long after they bought the child, Zhao Juan's parents passed away.

Zhao Juan felt that the child was a burden and sold him to someone else.

She took a deposit from the new family.

But because of the live streaming situation, she thought keeping the boy might still be profitable, so she didn't want to send him away so soon.

The boy's biological parents saw his photo on a missing persons website and came looking for him.

They coincidentally ran into the new family who bought the child.

This...

Whether to speak up or not, this point was also handled very precisely.

No one knew that I had posted the child's photo and information on the missing persons website, and I never brought it up again.

Do good deeds without seeking recognition.

This is a traditional virtue of the Chinese nation.
