Guangdong is China's most populous province and its economic powerhouse, located in the far south along the South China Sea. It encompasses the vast Pearl River Delta megacity region, including Guangzhou, Shenzhen, Foshan, and Dongguan. The province is the birthplace of Cantonese cuisine, culture, and language, and has been the gateway between China and the world for centuries. From the UNESCO World Heritage Danxia Mountain to the gleaming skylines of Guangzhou and Shenzhen, Guangdong offers a dizzying blend of ancient tradition and hyper-modern city life.
