Blue sea? golden beach? colorful undersea world? always let our hearts full of longing; childhood dream has always been a light small foot? carrying a smallplastic barrel? step on the soft sand? looking for a single and a beautiful shell;also once fantasized oneself is a mermaid in the sea? in their feelings and dreams to swim. After growing up? only to find that the sea is so far? far away in the far-off regions? dream is so miles away
