We really do need a genuinely fluent Chinese speaker that is for sure.
There's no way anyone could say that the "mistake" was due to translation problems on the English site, if they said the exact same thing on the Chinese site.
They could only claim that the Chinese site was erroneous due to some other reason (but not due to translation).
AND, if they do claim there was an error on the Chinese version then that error was introduced TWICE, once for the Chinese site and once again for the English site.
Seems to me like an awful lot of effort to put up an error and that error not get caught by the time the two versions of the sites went up.
But then, maybe it's wrong, maybe the above is wrong, maybe everything is just wrong, lol.
