Part of the lyrics: why not go out of the city and climb to the top of a high mountain, abandon the corrupt world and look up at the sky further away. White clouds are floating, and God is calling us. Do you have a crush at the critical moment of your life? Why not go out of the city, shake off the dust, dry the tears of regret and face the refreshing wind? We have seen through the emptiness in the world, knowing that it is vanity, why not go out of the city?
