I am a college dropout, but I was exposed to computers earlier than my peers. I taught myself simple programming when I was 15 years old and I was addicted to computer technology. My technology blog was written from the age of 17, during which I used typecho as a blogging system, but there were some security issues with dynamic websites, which led us to change to a static blogging system, and part of the blog data was lost, and now the blog content from 2020 to now.
