That's another point.
It sounds plausible to me, that they need US dollars for uplisting fees, attorneys or their US company holding. Everyone (me included) says, that is is almost impossible to get yuan out of China. Yet I cannot verify that for a fact, or just some repeated rumour someone has posted a while ago.
You can read some interesting passages about that in 10-Ks, stating that they need to be profitable and having paid an amount in some Chinese fund, until they are allows to pay dividends, which includes getting money out of china.
That's the one thing. But if this is the case, why didn't they write that explicitly write that in the offering, and not only "general purposes" and stuff...
More later, got to go.
