"We all treat Grandma Liu as our own great-grandmother," Liu said. "We take care of all the daily stuff for her and talk with her. She's a funny woman with a cheerful attitude and sometimes tells jokes to us."

However, when Xiong was first transferred to the rehabilitation center, she was like a totally different person. She was quiet and looked unhappy for quite a few days.

"At that time, she couldn't adjust to the environment at the center and was reluctant to have meals," Liu recalled. "She even raised her fist at us, thinking that it would threaten us away."
