To help for travelers in tourist area
Hello travelers;
there is some thing i want to let you know in my country.
In Vietnam, especial in Ho Chi Minh city at district 1 ( it is central of the city and where travelers stay and walk around) if you see some one wear the green police clothes like i have attached the picture below then they are just security and they will help you if you need to cross through street or explain the map for you to show you where you are and what on the map show. You can just feel free to ask them and they will be happy to help you.
happy travel - happy life!
Tran.
