This elaborate username combines several elements. '空城旧梦'(kong cheng jiu meng) refers to old dreams in an empty city. '凉薄荷'(liang bao he) is cool mint, symbolizing refreshing or cold feelings. '孤岛囚梦'(gu dao qiu meng) means being trapped on a solitary island, perhaps in one's dreams or desires. '酸柠檬'(suan nimen) represents sour lemon, adding a bitter twist. Overall, it suggests loneliness, nostalgia, confinement, and bitterness.
