I consider music as an artistic pursuit as much as the pursuit of pure math. The beauty in pure math is about the elegance of logic, reasoning, and problem-solving, while the elegance of music lies in its expressiveness and emotions beyond words. I created a YouTube channel to share the beauty of music and moments of my life.
