Abstract: The patron saint of ancient Chinese folk traditional culture has obvious regional characteristics. In Qing Dynasty, a large number of Han immigrants from other provinces moved to Yunnan, and the main body and content of Yunnan folk beliefs changed. With immigrants as the main body, the patron saint of the region characters and gods as the characteristics, the beliefs among the Han people with the village temple as the carrier of transmission were spread in Yunnan, and adjusted and integrated with the indigenization of immigrants, presenting the characteristics of multiple gods, secularization, and utilitarianism. The dissemination and development of the patron saint beliefs of immigrants are conducive to stabilizing the psychology of immigrants, enabling immigrants to accept, adapt, and integrate into their new homes; it is conducive to promoting the inlandization of frontier folk customs, enriching the content of Yunnan folk beliefs and culture, and making Yunnan folk beliefs and culture the coexistence and integration of multiple cultures.

Key words: folk beliefs, Han immigrants, spread, fusion
