Comments
The Scientific Research Center of Huashi Senior High School, Wuxi Jiangsu is now working hard on a project which is intended for a Nobel Prize for the school as well as more Nobel Prizes for China so as to add to the school’s reputation. Because of lacking in top talents, some teachers and students of this school suggest cloning some great people such as Tu Youyou, Mo Yan, Yang Zhenning and Madam Curie. They also hope to clone more than a thousand Li Hongjuns in order to enlarge the school’s talent reserve.
