After a hard long war, even the civil war between Nationalist against Communist, Chinese could defeat Manchurian and drive out the Japanese, European and American. In People's Republic of China, Mongolian and Manchurian even Tibetan are accepted as Chinese people. The Chinese religions and traditions were under pressure by Mao followers that made communism as the one and only culture, religion and tradition. The result of this extreme communism is not only the setback of religions and traditions but also the poverty among Chinese even until now. China started to accept capitalism and today China becomes the great economic power.
China is communism politically but in fact China is capitalism economically.
And capitalism creates big towns and new rich people with their western diet like consuming beef hamburger or fried chicken and these make the increasing demand of meat in China. Now, most people in China, especially who live in undeveloped villages, eat more vegetarian food than meat, not because of religious or traditional reasons but because they are too poor to buy meat. But economic growth and meat diet will change this condition soon. If most people in China eat more meat and leave the vegetarian diet, there will be a great environmental disaster.
