“Qingming Festival to worship the Yellow Emperor, Grain Rain Festival to worship Cangjie.” Legend has it that after Cangjie invented Chinese characters, “millet rained from the sky, and ghosts cried at night.” This is because the invention of writing changed the way humans recorded events, heralding the progress of civilization. The Cangjie Tomb and Temple in Baishui County, Weinan City, is home to ancient cypress trees, which, along with the ancient cypress trees at the Yellow Emperor Mausoleum in Shaanxi and the Confucius Temple in Qufu, Shandong, are known as the “Three Great Ancient Temple Cypress Groves of China.” They have high historical and cultural value.
