The priest and patron relationship, also written as priest-patron or cho-yon, is the Tibetan political theory that the relationship between Tibet and China referred to a symbiotic link between a spiritual leader and a lay patron, such as the historic relationship between the Dalai Lama and the Qing emperor. They were respectively spiritual teacher and lay patron rather than subject and lord. Chöyön is an abbreviation of two Tibetan words: chöney, "that which is worthy of being given gifts and alms", and yöndag, "he who gives gifts to that which is worthy".

Dalai Lama is a title given by the Tibetan people to the foremost spiritual leader of the Gelug or "Yellow Hat" school of Tibetan Buddhism, the newest and most dominant of the four major schools of Tibetan Buddhism. The 14th and incumbent Dalai Lama is Tenzin Gyatso, who lives in exile as a refugee in India. The Dalai Lama is considered to be the successor in a line of tulkus who are believed to be incarnations of Avalokiteśvara, the Bodhisattva of Compassion.
