China should build the super-collider to push the boundaries of particle physics further. The Higgs boson's discovery was groundbreaking, but many questions remain unanswered. China's larger collider could uncover new particles, supporting or debunking existing theories, and providing invaluable negative results. It also would foster high-tech industry growth in China and attract global scientific talent, invigorating its scientific community. Given its scale and technological demands, this collider could b
