Shang Chi's perfect amazing 10/10 parries and dexes help

Saquongoat

Has anybody mastered the art of Shang's perfect parries and dexes for extra chi charges? To me it seems to be random, but I'm sure there's a good way to figure it out. Thanks for any help

Not sure, but I think you just have to wait an extra few milliseconds, and parry/dex at exactly the moment of impact
