Zhang Chang (L) and his wife Haie pose in their cafe in Paris, October 17, 2013. Zhang owns the Cafe Le Maris in central Paris and is part of a wave of entrepreneurial migrants from China's coastal Wenzhou region who are taking over France's "bar tabac" business. While French workers worry the country's long economic downturn could mean the end of laws banning Sunday trading and enforcing a 35-hour week, Zhang and Chinese immigrants like him are quietly getting ahead the old-fashioned way - 11 hours a day, six days a week.
