"sea wide sky empty") is a Cantonese song written and recorded by the Hong Kong rock band Beyond.
[9] It has been adopted for several events in Cantonese-speaking regions, such as the Artistes 512 Fund Raising Campaign for the 2008 Sichuan earthquake, and most prominently as the unofficial anthem of the 2014 Hong Kong protests.
However, the band's lead vocalist Wong Ka Kui died on 30 June 1993, around two months after the song's release.
Beyond recorded a Japanese version, "Haruka naru yume ni ~Far away~" (遥かなる夢に 〜Far away〜, literally "A Faraway Dream").
In the 2003 Hong Kong movie Truth or Dare: 6th Floor Rear Flat, the song was performed live by Teresa Carpio, where it was interpreted as the sacrifice a mother had made for her son.
