A new life for JiaJia: From China to Missouri

CNN first met JiaJia in a Beijing orphanage in 2015. He'd been waiting for years to be adopted, since being abandoned by his mother outside a fertility clinic in Xinyang, Henan province. In January 2016, he was taken to the US by a new family -- the Wilsons -- who are determined to give him a better life. In December 2016, CNN went to catch up with JiaJia, now Jason, and see how he's settled into his new home in Missouri.
