Languages names, at the international level, are clearly defined by an international body and norm which is the ISO 639-3.
According to this norm, "Chinese" is a macrolanguage with code "zho", but not a "language" with code "cmn".
The official name corresponding to ISO 639-3 code "cmn" is "Mandarin Chinese" http://www.sil.org/iso639-3/cod...639_3&letter=c

I strongly support following international standards and thus, applying ISO 639-3 languages names in Tatoeba.

>was genau meinst du damit?

I mean that many Germans speak a local dialect + Hochdeutsch.

>es ist völlig unerheblich

Not at all. Maybe in your generation only, but you represent but a fraction of an ageing German population...
According to my experience, many Germans speak dialects, at least in part, in their everyday conversations, and I have seen from my own eyes and heard with my own ears, Germans from different regions of Germany who didn't understand each other AT ALL, although they were supposed to speak the same German language...
I have daily testimonies, including on Tatoeba, that German speakers mix their dialect with Hochdeutsch all the time and stand subsequently corrected. I bet you were a few times yourself, I'll dig into your history when I have some time to check it...
Of course, each individual is convinced he/she speaks a standard language...until others debate that...
A certain friend of mine who just moved from one part of Germany to another, and who ascertained before, the same way you do, that she spoke perfectly standard German, had the honesty to acknowledge that she just discovered that a few words she uses in her home region are just not understood or mean something different in her new home...
Unlike in France, where television and most radio networks are national, German networks are regional, and I think this is instrumental in giving Germans the feeling that their regional way of speaking is the norm...

>Like calling people senile because you disagree with their supposed opinions.

That's not why I call them senile. The Central Committee of The People's Republic Of China's Communist party's members average age revolves around 75. They're all senile. The cling to power and understand nothing of the modern world, and tremble at any dissent: they imprison artists, pacifists and bloggers, have nuns raped and monks tortured when they do not inoculate tubercolosis to Uyghur prisoners. And why are they so violent? Because they're scared. They are scared of Internet, they are scared of their own old shadows of fighting Kingdoms because they themselves created a society that is on the verge of explosion with such dramatic rifts between North and South, rural and urban, poor and rich, Han and not Han.
They resort to the most disgusting nationalism to make their people forget that they are just inept rulers, just good at poisoning their own grand children in the name of productivity, and spare on the concrete of new school buildings in seismic areas that collapsed on the pupils, while the money to make them earthquake-proof went into their deep pockets...
Chinese rulers make me sick, indeed, and I am not being fooled by their nationalistic propaganda that goes down to languages, in a very effective way. They go as far as to falsify statistics about ethnicities and spoken languages. The actual number of speakers of Mandarin as first language is completely over-estimated.

>Or denying the existence of an overarching superidentity to protect the overarched subidentities.

Well, there's nothing to prove or deny. "Chinese" speakers do not understand each other as French speakers do. They don't speak the same languages in everyday life. It's a fact.
