Li Jing Wei was only 4 years old when he was abducted from his home in South Western China and sold to a new family in a different province.
Being so young, Jing Wei says he couldn't remember his birth name, the names of his parents or his home address.
Determined to find his way back, Jing Wei painstakingly drew a map of the few buildings, paths and hills he could remember from his town.

He did this every day from the age of four till he was thirteen so he wouldn't forget.
"It was the only clue I had to find my home in the future," Jing Wei said, speaking via a translator.
More than 30 years after his abduction, Jing Wei posted his map to a Chinese social media site, along with a plea to help him find his family.
Amazingly, police got hold of his map and were able to identify the village he came from and used DNA samples to track down his family.
After decades apart, Jing Wei was finally reunited with his mother and two siblings. His father had unfortunately died.
Now a father himself, Jing Wei plans to visit his dad's grave during the Chinese New Year so they can all be together.
