I agree with you. Zijin Cheng must go into the 2100 Time Capsule. Since we are leaving the planet Earth, I might even expand your reasoning to include all of humanity. Zijin Cheng might represent the beauty and grandeur that human beings can achieve when they work together for a common goal. I loved learning that the building included spiritual and physical elements and that more than one religion was represented. Which religions, besides shamanism, got recognition?
