 The uneducated, rural, and mostly female street vendors are depicted as participants of "microbusiness" and local grassroots economic development by business reports.In July 2008, Hanoi's city government devised a policy to partially ban street vendors and side-walk based commerce on 62 streets due to concerns about public health and "modernizing" the city's image to attract foreigners.Many foreigners believe that the vendors add a traditional and nostalgic aura to the city, although street vending was much less common prior to the 1986 Đổi Mới policies.
