Photo taken on Sept. 3, 2016 shows a corner of the Alibaba headquarters in Hangzhou, capital city of east China's Zhejiang Province. Thousands of smaller online shopping businesses are clustered in Hangzhou, home to e-commerce giant Alibaba. The city, praised by Italian traveler Marco Polo in the 13th century as "the world's most magnificent and noble city," is little-known compared with Beijing and Shanghai, but has much to offer and is a window on new trends in China.
