Welcome to my blog. This is where I document my learning and hands-on practice in computer science and related fields. My focus is on the underlying principles — starting from foundational concepts to explain the essence, design logic, and working principles of technology. The goal is to make these ideas accessible to beginners and non-experts, while offering experienced readers a systematic framework for consolidation and reinforcement.
My published articles are also available in English. Each English edition links to its Chinese original.
