The Red Flag Canal—originally known as the "Project to Divert the Zhang River into Linxian County"—is located in the northern part of Linzhou City, Anyang, Henan Province, near the junction of Henan, Shanxi, and Hebei provinces. As a water conservancy project turned tourist destination, it is designated as a National AAAAA-level Tourist Attraction and a Major Historical and Cultural Site Protected at the National Level, covering a total area of 24.16 square kilometers.
Often referred to as an "artificial river in the sky," "China’s water Great Wall," or the "eighth wonder of the world," the Red Flag Canal has been featured in primary school Chinese language textbooks and the eighth-grade *Chinese History* curriculum. It has earned numerous accolades, including recognition as a Key Scenic Area, a destination for "red tourism" (revolutionary-themed tourism), an exemplary national tourism organization, and a benchmark for high-quality development among national water-conservancy scenic areas. The "spirit of the Red Flag Canal" has also been incorporated into the "first batch of great spirits in the spiritual lineage of the Communist Party of China." In January 2023, the site was included in the *Directory of Water-Conservancy Scenic Areas with Revolutionary Heritage* and the list of water-management projects recognized under the theme "A Century of Achievements in Water Governance by the People."
