Good morning!

Oh, and in case I don’t see ya—

Good afternoon, good evening, and good night!

I’m Longfei, a PhD student at Beijing Normal University.

I’m passionate about understanding human behavior, psychology, and the world through mathematical statistics and machine learning. I love discussing these topics, so feel free to reach out!

What we know is a drop, what we don't know is an ocean.
