who am i?

I am a high school student from Shanghai. I have few friends, I am not good at socializing with people, and have always been alone. I used to be the president of the school robotics club, but I withdrew because I needed to prepare for the college entrance examination.

I am a technical geek familiar with computer and electronic technology. Because any sufficiently advanced technology is indistinguishable from magic, I am also trying to become a magical girl. XD.

I am studying Japanese. Although the actual level is not very good and I am not confident, I think I can pass the Japanese Language Proficiency Test (JLPT) N2.


I learned many things, but not proficient.
I am operating my own Internet autonomous system.
I have experience in CTF, but I don't know how to write algorithms in OI at all.
I hold the China's Amateur Radio Operation Licence level B, and can transmit and receive on all amateur radio frequencies.

I have no direction in learning, and I only start learning when I need to use it.

I ardently love cute illustrations, gal games and animations.
ACGN is an indispensable part of my life.
You can see my ACGN life record on AniList.

I am also interested in various electronic devices, such as amateur radio transceivers and calculators.

I will take the National College Entrance Examination in 2022.
I have poor academic performance, and I don’t know what university I will go to in the future.
I will most likely apply for these majors.

  • Computer Science
  • Electronic Engineering
  • Computer Engineering
  • Software Engineering
  • Network Engineering
  • Information Security
