Yu Ya indeed did not kidnap Nian Nian; it was a spur-of-the-moment decision by that woman.
When Nian Nian got lost, he was found by a security guard at a supermarket near the house.
After the security guard asked for contact information for Nian Nian's family, he got an international phone number.
The security guard hesitated before taking Nian Nian, intending to send him to the nearby police station.
Unexpectedly, he encountered Yu Ya on the way.
Yu Ya was one of the shareholders of the supermarket where the security guard worked and his direct supervisor.
When she saw the child with the guard, she immediately recognized Nian Nian.
She asked the security guard where the child came from.
The security guard told the truth, and Yu Ya said, "Leave the child with me; I know his father."
Although the security guard was a bit surprised, he saw Yu Ya squat down and say to Nian Nian, "Is your father's name Wen Linyu?"
