They say that Benny's speaking ability is about the HSK-3 level ("... he definitely reached B1 level. For the HSK, HSK 3 is supposed to be B1, ...").
But he would fail the HSK-3 because he is unable to recognize and to write Chinese characters. ("... though he would struggle with the characters ...").
One should ALSO keep in mind that HSK-3 is NOT EQUIVALENT to CEFR "B1" as they state in the article. As stated from the Association of Chinese Teachers in German Speaking Countries on the new HSK, the HSK-3 is equivalent to CEFR "A1" (!!!) which seems much more realistic from what we saw in the videos (he didn't speak a lot, and I wonder whether he understood a lot!).

I think the article is a just big ad for the language school, and for Benny of course!
If I would visit this school, they would never write such a long evaluation about my Chinese!
