"I was going to kindergarten and there was a man and a woman," Luo says. "I thought they were friends of my father so I went with them.
"I was transferred from car to car. Later on I was told I was in a mountainous area in Fujian province."
The bewildered schoolboy had been taken to Sanming, 1,500 km (900 miles) away where life with a completely different family awaited him. Luo was given a new name and introduced to a new sister.
He had become one of thousands of children abducted every year in China, very few of whom will ever return home. The country's one-child policy and lax adoption laws has fuelled an underground market for trafficked children. Earlier this year a police chief in Fujian claimed over 10,000 children had been trafficked in 2012 in his province alone.
