Welcome! This is OverflowCat’s blog. Here I write about programming, optics, language learning notes, my weekly life, and more.

The domain or site name, xīnshìjièdemén, lit. “the gate/door to a new world”, is a Mandarin slang that describes a brand new experience, such as learning a new language or crossdressing for the first time. By using this term as the site name, I hope I am writing something new and inspiring.

You may have noticed that there are some slogans go beneath the site name. They are actually quotes from poems that contains the word “world” in them:

  • So fancy is the world, who knows, maybe they sing

(Mary Oliver’s This World)

  • Those that cannot be praised praise the world

(Title of a poem from 木叶)
