Chengdu, where it is located

The climate of Chengdu is temperate, with relatively cold winters, and hot, muggy and rainy summers. Chengdu is the capital of the Sichuan Province and is located in southwestern China, at a fairly low latitude (at the 30th parallel), but also in a vast continental zone, 1,100 kilometers (685 miles) away from the sea, 500 meters (1,650 feet) above sea level, and a short distance from the mountains, so it is quite cold in winter, while in summer, it is not as hot as nearby Chongqing (which is famous for being a hot city).
Here are the average temperatures.
