求雨, or "praying for rain," is a traditional practice in various cultures, particularly in agricultural societies. It involves rituals and ceremonies aimed at invoking rain to alleviate drought and ensure a good harvest. These practices often include offerings, chants, and dances performed by community members. In China, 求雨 has historical significance, with many ancient texts documenting the rituals performed by emperors and local leaders. The ceremonies often take place at temples or sacred sites, where participants seek the favor of deities associated with rain, such as Tian or Shangdi.
