This pattern, which many people can't understand but marvel at, stems from Jackie chan's essential obsession with cleanliness and obsessive-compulsive disorder: he is a person who can't stand to be irregular, not clean, not neat. Seeing the mess of the site, He started to clean it up. Seeing the dirty floor, he swept the floor with his hands. After drinking water, He squeezed the empty bottle and recycled it. But Jackie chan never CARES what other people think, because it seems to him that all this is so natural and his way of life. He did it not for others, but for his own pleasure。
