Liu Liu is one of the volunteers who conducted a survey on the effectiveness of the Xiao procedure, which was claimed by the inventor, Dr. Xiao Chuanguo, to have a rate of success of 85% for treating urology diseases (spinal bifida) by surgery. During the week of November 10, she visited several patients who had the surgery. Because the patients lived in different places, Liu Liu had to travel through a number of cities including Chengdu, Meishan, Deyang, Guangyuan in Sichuan province and from Linfen to Gaoping in Shaanxi province, in the cold, snowy days. Upon her return on November 18, she was interviewed by the Science Journal.
