Zhu Junlong was an abandoned baby. He was taken in by a Chinese family that had taken good care of him since he was young.
He may not be a Chinese but he was treated as part of the family.
His Chinese grandmother found him at a small alley at a bush jungle.
It was a hot summer so he could have died from sunstroke without help.

His son, who was married for three years then, did not have a child yet.
By adopting Zhu Junlong, it would save his life as well as satisfy the desire of his son and daughter-in-law in getting a child.
His grandmother did not think about how she was going to raise him but her only thought was to save a life.
This is a great example of how love can go beyond the physical outlook or differences.
The unconditional love for Zhu Junlong by accepting him just the way he was.
