Unknowingly, we have gone a long way in the journey of time. Every beautiful or painful experience along the way will be exiled into this sea of time, and those memory fragments will disappear and appear in the mind, causing waves from time to time. As Mr. Hayao Miyazaki said: "You will never forget what happened, you just can't think of it." If you really don't want those fragments to sink into this "sea" forever, you can catch them in time and piece them together into complete or incomplete paintings, so that the beauty of the past can stay with you for a long time.
