Businesses in Vietnam are also very different from what we can see here in America. Groceries stores, banks, restaurants and other businesses here are usually located at a certain area that is separated from neighborhood. However, in Vietnam, most businesses are mixed in with other areas. Because of the its population of over 7 millions people, building structures are commonly wall-to-wall and level up. There can be a supermarket, a bookstore, or even a hospital next to peoples’ houses. More than that, there are a lot of small businesses which is self-operated by home-owners. They can use up their own home space to open up a casual and neighborhood-friendly small business such as a convenient store or a coffee shop, etc. This is one of the most popular choice to generate income of old people and retirees in Vietnam because of its relaxed and simple business structure.
