Obtaining exact numbers of practicing Buddhists can be difficult and may be reliant on the definition used. Adherents of Eastern religions such as Buddhism with local Animism, Chinese folk religion, Confucianism, Shinto, and Taoism often have beliefs composed of a mix of religious ideas. While only a small proportion of the population may have taken the formal step of going for refuge, many more may practice an informal Buddhism or hold Buddhist beliefs mixed with those of related religions. This is particularly the case in East Asia, where Buddhism has long been practiced alongside Taoism and Confucianism in an arrangement sometimes known as the "Triple Religion" or "Great Religion". The Religion in China, Vietnam, Japan, Korea; Vinegar tasters; Sinosphere; Neo-Confucianism; East Asian Buddhism and Buddhism and Eastern teaching articles discuss this phenomenon in greater detail.
