A tour in HANOI is to steep yourself in history, tradition, and legend in a capital that has been inhabited continuously for almost a millenium. Visitors often note that the city is quieter, greener, and "cooler" than other big cities of Vietnam. Indeed, Hanoi itself, and the Northern Vietnam, have quite clear four seasons, and October to March are lovely pretty cool months whilst other towns southward just have dry and rainy times. It probably influences in the mentality of the inhabitants and the city seems attract more intellectuals and artists, while Saigon is great for entrepreneurs and hustlers.
