Fairy immigrants, what do the lyrics mean?

The lyrics mean that Hong Kong is in a golden age, and immortals will emigrate to Hong Kong. According to relevant public information, Danny Chan, the singer of Immortal Immigrants, wrote lyrics for Lu Yongqiang. The lyrics are that there are eight immortals in heaven. I only know that one day, the sky survey will never change and I don't know the development of the world, but one day my feet slipped from the clouds and fell into the dust (I saw a smiling face). Seeing a Cantonese film on TV, the traffic lights are flashing, and the immigrants want to make a decision.
