Weibo said that his official resume said that he had a master's degree in economics and a doctor's degree in engineering, but he could find a doctoral thesis without master's information. When he was an economic counselor in Japan, his wife got a "monk's degree" from Nagoya City University, but it was an honorary certificate, not a degree certificate. Liu once asked the school to add the word "degree" and change "assessable equivalent academic ability" to "special training for awarding degrees", which was rejected.
