Go to any website, copy-paste some text into it,
(for example, this website
https://suulnnka.github.io/BullshitGenerator/index.html?%E4%B8%BB%E9%A2%98=%E4%B8%AD%E5%8D%88%E5%90%83%E4%BB%80%E4%B9%88&%E9%9A%8F%E6%9C%BA%E7%A7%8D%E5%AD%90=1072558877
is used to generate a lot of meaningless Chinese words to test text render.)

then, it begins slowly.
