That is not accurate.
Chinese citizens having gold on hand IMPLIES a loss of faith in the RMB.
I don't see RMB being a sole reserve currency nor will the dollar collapse completely.
I think there might be a transition to a system dominated by USD, Euro, and RMB with gold playing a large role as well.
Fall of the dollar will result in decreased confidence in fiat currency. What happened to the dollar can easily happen to the RMB.
