Chengdu experiences pleasant springs, hot and humid summers, cool autumns and temperate but damp winters (averaging 5 ºC/41 ºF). July and August can be uncomfortable, with temperatures reaching 35 ºC (95 ºF). In the heat of the summer, many locals seek relief in weekend mountain retreats or venture out after sunset to do business, shop and eat. Summer also sees periods of heavy rain. The best time to visit is between March and June or between September and November when it’s cooler and less rainy. One explanation for the locals’ love of hot and spicy food is that the chilies and pepper help the body cope with the damp climate.

The administrative seat of several ancient kingdoms, Chengdu has a 2,300-year history as an important center of study and trade. In the early fourth century BC, the ancient Shu state established a capital in today’s Chengdu. The conquering Qin State (778-207 BC) enlarged the city, adding an impressive wall. During the Western Han Dynasty (206-225 BC), the city was called Jincheng (Brocade City) after its thriving silk brocade industry. Once the Han Dynasty fell, giving way to the bloody Three Kingdoms Period, Chengdu became capital of one of the Shu Han (Kingdom of Shu).

The city continued to develop as a regional center into the Tang (618-907 AD) and Song Dynasties (960-1279 AD) and is known for certain innovations—for example, paper money was first printed and used in Chengdu during the Song Dynasty. During the Tang Dynasty, it was home to China’s best-known pair of poets, Du Fu and Li Bai, perhaps the most famous of many artists and writers who have lived and worked in Chengdu over the centuries.
