Childhood nostalgia always brings along happy moments. In 1978, we, friends of the bride and groom's parents, had just graduated from high school and entered the university. At that time, we were all less than 18 years old (age of maturation in Vietnam).

No one expected that the war happened soon after, which brought drastic changes to our lives. There are things that are forever lost from our lives. One of them is the special drink called "Bao Bao Luong Xa" sold by the Chinese in Hanoi. It was a very delicious drink, but too expensive for us children, so when we saw them yell on the street trying to sell this drink "Bao Bao Luong Xa ", we all yelled back " Ngã đo sàn nhà ", which is loosely translated to “Pass out on the floor” (to reflect our reaction to our unfulfilled desire to have it)
