Panjin is a prefecture-level city and a major oil-producing city in Liaoning Province, China. It has four distinct seasons, an annual average temperature of 8.6C and receives over 2700 hours of sunshine a year. There are over 1.3 million people living in the Panjin area. Administrative history of Panjin Area can be traced back to 195BC during the Han Dynasty (206BC-220AD). The Tang Dynasty (618AD-907AD) brought the region back from the Koguryo Kingdom to the regime of Central China. Panshan is the earliest county established in modern Panjin. The Red Beach is located in the Liaohe River Delta, about 30 kilometer southwest of Panjin City in China. The beach gets its name from its appearance, which is caused by a type of sea weed that flourishes in the saline-alkali soil. In autumn, this weed turns flaming red, and the beach looks as if it was covered by an infinite red carpet that creates a rare red sea landscape.
