Built in 1901, the six-kilometer-long Huai Hai Road formerly named Avenue Joffre, commemorates the Huai Hai Battle during Liberation. Today, this road has become synonymous with what is trendy and fashionable in Shanghai. While the stretch between Shan Xi Road and Xi Zang Road is the busiest section (and best for people-watching), this commercial street contains more than 400 shops, restaurants and businesses. The remnants of French architecture give the street its cosmopolitan charm. Many nearby attractions add to its appeal, including the proximity of Doctor Sun Yat-sen Former Residence and Memorial Hall.
