The young girl who survived 2011's deadly high-speed train crash will only suffer from a lesser degree of disability than expected, according to a medical appraisal of her injuries.

Four-year-old Xiang Weiyi, nicknamed Yiyi, was rescued from the train accident that killed her parents on July 23, 2011, 20 hours after two bullet trains crashed near Wenzhou, Zhejiang province, claiming 40 lives. The girl's left leg was badly injured.

Yiyi has been receiving treatment and rehabilitation in Shanghai for several months. Her uncle Xiang Yuyu provides updates on her progress on Sina Weibo, a micro-blogging platform.
