How to remember it
Reading a figure once rarely fixes it in memory. Attach Hanoi to a place and a number you already know: it is 478 km from Vientiane, and it is the 21st largest capital in the atlas. Then practise retrieving it. DailyGeo Capitals gives you one mystery capital a day with distance, direction, language and population clues, the memorising method explains the review schedule, and the capitals index lists all 172.
To see how Vietnam compares with every other country on figures like these, the most expensive Big Mac index ranks them on geopolitix, a country-ranking game by the same maker as DailyGeo.
