CHONGQING, China (CNN) -- Anna He is like a lot of kids about to turn 10. She plays with her brother, fights with her sister, practices piano, hates vegetables and is adapting to her new life -- adapting, because even though she's Chinese, this little girl seems far from happy about living in China. 

Anna He, 9, finds it hard to adjust to life after she was returned to her biological parents, Jack and Casey He. 

"I always hate staying in China," she says. "It's one of the worst places I have ever been. When I first went to the big city, there was so [much] pollution and so [it] always makes me feel bad. I also don't like the smell." 

Her new life in China began after the Tennessee Supreme Court ruled last year that Anna should be returned to her biological parents, Jack and Casey He, known in China as He Shaoqiang and Qin Luo respectively. 

The decision ended a six-year custody battle. 

Anna was born prematurely while her parents were in Memphis, Tennessee, on temporary work visas. Unable to cope financially, they decided to give her up temporarily until they were able to get back on their feet. 

That's when Jerry and Louise Baker stepped in and agreed to take temporary custody of Anna, when she was 4 weeks old. The Bakers said they made a verbal agreement with the Hes to take care of Anna until she was 18. 

But the Hes dispute that. They wanted their daughter back soon after her first birthday and eventually went to court to have their parental rights restored. After a bitter legal battle, the Hes finally prevailed and Anna was returned to her parents. Anna was given a six-month transition period to adjust to her biological family before the Hes left the United States.
