This page is auto-translated from [/nishio/Oral Keichobot](https://scrapbox.io/nishio/Oral Keichobot) using DeepL. If you looks something interesting but the auto-translated English is not good enough to understand it, feel free to let me know at @nishio_en. I’m very happy to spread my thought to non-Japanese readers.
