Who makes Wanyu, and how the content is made
Wanyu is run by Brais, a Chinese learner who built the app he wanted to use and couldn’t find. This page tells you who’s behind it and, in the same detail, how the content is made — without pinning on a badge of authority it wouldn’t have.
Who is Brais?
Brais is Spanish, and he runs Wanyu. He started learning Chinese the way most people outside the English-speaking world do: with whatever materials existed, and almost all of them were in English. Years later he handles the language at around HSK 5, and along the way he kept hitting the same problem — until he decided to solve it himself.
Studying Chinese through English, when it isn’t your native language, makes you translate twice in your head. But comparing the two languages, Brais noticed something that helped rather than got in the way: some nuances of Chinese land better with an English gloss, and others click sooner in Spanish. Instead of picking one, he thought, why not see both at once? That’s why Wanyu shows every word with the gloss in both languages at the same time (and you choose which to show or hide): two perspectives on the same word, so you understand it from more angles.
Wanyu came out of that concrete need: the app Brais wanted to use didn’t exist, so he made it. He’s its first user and its most demanding tester — nothing reaches the app until he has actually used it while studying.
How is the content made?
Honesty first: there’s no team of credentialed sinologists behind Wanyu, just a student with a serious working method. We’d rather tell you how it’s made than fake an authority we don’t have. The content is built in batches and passes several review gates before it reaches the app.
The 11,323 cards cover the official HSK 3.0 standard (norm GF 0025-2021, which lists 11,092 words). There are more cards than words because words with more than one reading are split into one card per reading.
Where do the HSK levels come from?
From the official standard, never from a guess. Each word’s HSK 3.0 level comes straight from the norm; the HSK 2.0 tag is shown alongside only when one exists. We never convert levels “by eye”: the two systems don’t map onto each other, so showing them side by side is the only honest way to do it.
How are the glosses and sentences written?
The English and Spanish glosses and the example sentences pass several review gates: a syllable-by-syllable pinyin check against the library itself, and a hand review of the levels and of the words with more than one reading. The dictionary glosses derive from CC-CEDICT; nothing doubtful is invented — it’s flagged. The grammar (371 points) and the chengyu (140) are written the same way.
What if I find a mistake?
It gets fixed. Any errors that reach us at support@wanyu.app are corrected in the next update. The content is reviewable and improves with every version: if you spot something wrong, write to us and we’ll fix it.
