China's left-wingers have been singing a high-pitched note in various media for a long time. ANBOUND think tank scholars consider that both the left-wingers and the right-wingers have their rights and room to express views. However, a genuine respect can only be attained for the left-wingers through a rational approach. It is a dream of many people for China to rank in the top countries of the world, but this goal is never easy to achieve, requiring both effort and opportunity. Nonetheless, prior to objective conditions, China must build up a solid social consensus that cherishes rationality, avoiding the "Kang Youwei Trap". Otherwise, not only can’t the goal be achieved, but also China will be trapped into a long-term turmoil, not even to say other things.
