1o10 Some situation

  • My CTF career started on 24 August 2020, and participated in CTF Competitions for about two years.
  • To get an admission for recommended postgraduate at school, I must keep the high GPA, so I gave up CTF after getting the CISCN National Prize and spent tooooo much time on studying to keep my GPA and rank.
  • In September 2024, I re-started my CTF career as a member of SUS in Cryptography.
  • As I have entered Master Grade 2 in September 2025, maybe there will be fewer CTF competitions for me to participate, so I will focus on my research and participate in some other competitions related to cryptography.
