About Me

I am passionate about programming language implementation, virtual machines, and compilers. Currently focusing on Python virtual machine internals and compiler optimization. I enjoy writing technical articles and have published over 120 articles about Python internals and computer systems fundamentals.

I believe that happiness, love, and passion should be the primary pursuits in life, ahead of study or work. Programming is not just my profession - it's my hobby and passion. I find joy in creating and understanding how things work from the ground up.

Always maintaining curiosity and the desire to explore is what keeps me moving forward. I believe that staying curious and passionate about learning is the key to both personal growth and happiness in life.

"What I cannot create, I do not understand"
- Richard Feynman
"The most important things in life are to love and to be happy, everything else comes after"
