-------------------------------------------
I copied the English version to the Chinese part of the documentation.
[~xtsong], maybe you can take a look that I did everything right?

> Currently it seems that it's not mentioned anywhere what's the number of
> required number of buffers. And that this number is different than the
> configured number of exclusive/floating buffers. It should be mentioned in
> that both {{taskmanager.network.memory.floating-buffers-per-gate}} and
> {{taskmanager.network.memory.buffers-per-channel}} are best effort and not
> guaranteed.
