    }I enjoy hiking in deep mountains and exploring cities on foot. I have witnessed glaciers and oceans, and visited satellite launch bases. I love gazing at the starry sky while also observing the veins of a leaf or the structure of a snowflake. I take pleasure in capturing these wonderful moments with my camera, contemplating how a waterfall's descent transforms gravitational potential energy into kinetic energy, and realizing how the starlit sky showcases the magnificent performance of gravity and nuclear fusion.
