Are Chinese coins still used today?

Are they still widely circulated and accepted as a form of payment, or have they been largely replaced by electronic and digital payment methods? I'm interested in understanding how traditional currencies like Chinese coins are adapting to the evolving financial landscape. Thank you in advance for your insights.
Is golden rice used today?
Is golden rice currently in use? Has it been widely adopted by farmers or is it still in the experimental stages? Has it proven effective in reducing vitamin A deficiency in those who consume it?
