As one of the Historical and Cultural Cities of China, Zigong is called "Lantern Town in the South Kingdom". In recent years, although the annual lantern show forces the local residents endure unpredictable and extended blackouts during China's Spring Festival, the lantern show is a boon for tourism in the remote but tranquil city and generates large revenues for the local government. The pattern of Lantern Show, a paradigm of China's festival economy, has been copied throughout China, which dilutes the uniqueness of Zigong's original version.
