Why does Niuyangge fall? People's hearts. A small number of people build, while the majority take from it. Many people's little thoughts prevent them from working together effectively. Why does Ai Wuwu fall? Since Niuyangge is falling, Ai Wuwu is falling even more, because those who understand know that Niuyangge still has people investing money, while Ai Wuwu is just shouting. Once it falls, they stop shouting and move on to the next one. Actually, I really hope Niuyangge recovers. I didn't buy in; I’m afraid of building it. Human nature is complicated.
