I'm Lin Xia, a computer novice who has just figured out PS and Python. The cutout problem in the computer room was solved by the boy at the next table; the smoke from the fireworks in my hometown's yard was mixed into the pixels and codes by me. When the locust leaves swayed on the screen and the tunes of Qin opera floated out, I discovered that the gentlest human fireworks were hidden in the cold code. This is a short story about growth, family affection and gentle encounters on campus. I hope it will warm you.
