The video starts with images of a block apartment ,which symbolized the monotone of Vietnamese architecture before "Doi moi" (Rennovation) in Vietnam.
As the economy started to boom in the 90s, people living in public apartments began to modify their rooms as they wanted. The results is a mixture of "same same but different" apartments.
The block apartment is a place where "juxtaposition" is interpreted to the fullest meaning. It's the constrast of public living and individual identity, of Soviet-era architecture and capitalist architecture.
In this case, the disorder is an act of escaping from the hardship in the pre-Doi moi era, adding the diversity to the beauty of Hanoi.
