CTB (China Thinks Big), known as the "Global Youth Research and Innovation Forum," is modeled after Harvard University's flagship program "Harvard Thinks Big." In 2012, the program was introduced to China through a collaboration between Harvard Business School and relevant institutions at Tsinghua University. It has since evolved into an international academic platform that spans 18 countries and regions, engaging tens of thousands of high school students. Guided by its core philosophy of "Think Big, Start Small," CTB encourages young people to identify concrete issues in their immediate environment and apply their knowledge and skills to drive tangible change.
