Nanning, also known as Yong, is the capital of Guangxi Zhuang Autonomous Region of China, a modern city with harmonious coexistence of many ethnic groups, mainly Zhuang. It is the centre of Guangxi politics, economy, culture, and transportation, making Nanning the core city of Beibu Gulf Economic Zone. The city is also the permanent host for the China-ASEAN Expo. Green is the symbol for Nanning as half of the region is covered by rich evergreen scenery. It is therefore known famously as “the Green City of China”.
