Weixinism, institutionally also known by the extended title of Holy Church of the Heart-Only is one of the Chinese salvationist religions born in Taiwan in the late 20th century. It was founded in 1984 in Taichung by Grand Master Hun Yuan. Its global core membership is about 300,000, with a larger audience estimated by Taiwan's Ministry of Internal Affairs at 1,000,000. The church has quickly spread to mainland China since the early 2000s, where it functions as a platform for joint initiatives of the Chinese mainland and Taiwanese governments for the renewal of Chinese culture. It has also developed as a worldwide religious movement, attracting followers not only from the Chinese diaspora, but also communities of other races, including East Asians and even Westerners.

Chinese salvationist religions or Chinese folk religious sects are a Chinese religious tradition characterised by a concern for salvation of the person and the society. They are distinguished by egalitarianism, a founding charismatic person often informed by a divine revelation, a specific theology written in holy texts, a millenarian eschatology and a voluntary path of salvation, an embodied experience of the numinous through healing and self-cultivation, and an expansive orientation through evangelism and philanthropy.
