History: Then And Now, China

Buddhism in China was first introduced from Central Asia during the Han dynasty and became very popular among Chinese of all walks of life, embraced particularly by commoners, and sponsored by emperors in certain dynasties. Mahayana (Dacheng, 大乘) is the predominant form of Buddhism practiced in China, where it was largely Sinicized and later exported to Korea, Japan and Vietnam. Some subsets of Mahayana popular in China include Pure Land (Amidism) and Zen. Buddhism is the largest organized faith in China and the country has the most Buddhist adherents in the world. Many Chinese, however, identify themselves as both Taoist and Buddhist at the same time.
Ancestor worship is a major religious theme shared among all Chinese religions. Traditional Chinese culture, Taoism, Confucianism, and Chinese Buddhism all value filial piety, or a love and respect for one's parents and ancestors, as one of the most important virtues. Chinese people generally offer prayers and food for their ancestors, light incense and candles, and burn offerings of Joss paper. These activities are typically conducted at the site of ancestral graves or tombs, at an ancestral temple, or at a household shrine.
Islam in China dates to a mission in 651, 18 years after Muhammad's death. Muslims came to China for trade, dominating the import/export industry during the Song Dynasty. They became influential in government circles, including Zheng He, Lan Yu and Yeheidie'erding, who designed the Yuan Dynasty's capital, Khanbaliq. Nanjing became an important center of Islamic study. The Qing Dynasty waged war and genocide against Muslims in the Dungan revolt and Panthay Rebellion.
Judaism in China dates to as early as the 7th or 8th century CE. In the first half of the 20th century, tens of thousands of Jews from Europe arrived in Shanghai and Hong Kong during those cities' periods of economic expansion, seeking refuge from the Holocaust. Shanghai was notable for its volume of Jewish refugees, as it was the only port in the world to accept them without an entry visa.
