The China Import and Export Fair (to give it its official name) is a bi-annual event held in Guangzhou since 1957. It is the largest of its kind in China, with 15,800 stands available at its gargantuan purpose-built halls in Pazhou, southeast of the city. The Spring session runs from April 14 to May 5 while the Autumn session runs from October 15 to November 4, both in three phases for different categories of products. During these times, accommodation prices in the city double or triple, and metro lines and buses to Pazhou become unbelievably busy. For more details see cantonfair.org.cn/en or phone 020 28888999.
