Children in Vietnam may be named as in order of birth. The first born may be named Ca (which means big/biggest), the second child Hai (means two), the third child Ba (means three) and so on.
Caged birds (for example, sparrows) are often seen on sale in the cities of Vietnam. They are not to be kept as pets (except rare expensive one), but for followers of Buddhism to buy and release into the sky, thus earning them extra merit in life.
