好的电影也许就是表达一种执念,若人人都放下我执,哪来的各美其美,美美与共。Ghosts are like wind, cant be seen initially, but if you add air pressure on it, it becomes storm, which can increase in both speed and size. And then? when that mixes with water vapor, it creates an electric charge. Finally we will see, the shape of an actual storm.
