Can Kelly's nationality be transferred to China?

I can't. According to the data of China's nationality management, Kelly's nationality can't be transferred to China, because China's requirements for people who transfer China's nationality indicate that the transferred nationality can't be transferred back at will. Kelly immigrated to Canada with his parents in 2004, so he changed to Canadian citizenship. Kelly was born in Dalian, and her ancestral home is in Liaoning, China.
