Uncle Ho, after whom Ho Chi Minh City was named (previously Saigon), has been dead for a number of years and his legacy still lives on - on the dirty walls, in the beautiful parks and on larger-than life billboards around the city. His strong paternal instinct is often one of the most depicted subjects, showing him with the children of Saigon and the five rules he gave them by which they should live their live: They stuck them up on the walls (and still do in most schools) and the children had to recite them daily. Be honest, be modest, and be brave. They also concerned conduct towards your elders, parents, teachers and each other. Also, always take care of personal hygiene. I'm sure they were put more eloquently but that's basically what it comes down to.
