he video originally is a concert visual for a Cantonese Hip-Hop Group "LMF" in Hong Kong.
Title of the song "返屋企" means Be Home in Cantonese.
To briefly describe the lyrics , since 1997 Hong Kong has been returned to China, there was a wave of emigration from HK for the fear of socio-political issues. The song encourages Hong Kongers take pride of, and love their home, Hong Kong, no matter where they have been.
Features of Hong Kong like high-rise compact buildings, bamboo scaffolds, neon signs, metro station names etc. were used as visual elements to create a journey of going home.
