The chances of coming across this font once in a lifetime are not low. You may have accidentally visited a red website or your kid recently ordered something from Temu, with a manual written in this exact font.
But have you ever wondered why this exact font is still used by CJK (Chinese, Japanese and Koreans)?
After 25 years, I just did, and I find it quite interesting.
In short:
There is a font called SimSun aka “the Times New Roman” of Simplified Chinese, primarily found in Windows OS and developed by Beijing ZhongYi Electronics Co. Ltd. in 2001.
It dominated the Chinese printing presses and, to a slightly lesser extent, digital content.
This font is a legacy of early computing in China, where it was chosen for its wide availability and compatibility. It became the de facto standard for Simplified Chinese text.
As most of the content is in Chinese, there was not much attention given to Latin characters due to it being a secondary concern - it supports it and that's it!
For curious minds:
There are more than 20,000 glyphs in a simplified Chinese font. And such fonts often weigh 5–10MB.
Yes, that’s a lot – enough to impact First Contentful Paint on websites with this locale, unless you take measures to optimize it. As far as I know, it is still an ongoing challenge in China.
As said earlier, any non-CJK character is secondary, and it has to adapt to the form factor of the Chinese characters. Differences in space and style of Chinese glyphs affect Latin characters too. Therefore, there wasn't much importance given to the style of Latin characters. It just supports them.
Most, if not all, Chinese characters are nicely fit in a square box of reportedly 1em with even spacing all around – you can lay them out vertically, horizontally or diagonally – and they'll look roughly the same. Roman characters, on the other hand, are slightly different – there are characters like “l”, “p”, “q” that usually differ in dimensions.
As I write this in Microsoft Word using the same font, I noticed an odd effect – the space after the apostrophe is as HUGE as my student loan!
This is because SimSun was designed to be a monospaced font, meaning each character occupies the same amount of horizontal space. This is great for Chinese characters, but not so much for Latin characters. It is part of the reason why you might see it often in Chinese manuals, product descriptions, and even in some Chinese websites.
It is there by default, and I can guarantee that manufacturers producing your massage gun for 2 euros and 99 cents don’t care about the font they use, as long as it is accessible and gets the job done.
Fun fact:
It is also legendarily referred to as “SimSun 12pt” – 12pt because it is allegedly the perfect size for “body” paragraphs."
I admit having had unpleasant associations with it, mostly aesthetically. It used to remind me something cheap and low quality. But I really embrace it nowadays.
You may also see it being an inspiration for Nothing OS’s default font.

A quick web inspect of their website shows it as NType82, but we can all agree that it is heavily inspired by SimSun.
I think it has unintentionally become a very iconic font with its own cultural history, and Nothing just pushed it a little further by delicately integrating it into their devices highlighting their taste in design and culture.
