Which is better ? Chinese version or global?

Hello
If i purchased a global version of the device: M3 Note
And that a number: “L681H” Or “M681H”
Can I install the Chinese version of the system?
Because I own a device: M2 Note, and I find that the company supports the Chinese version a lot of updates, unlike the global version!
Please help and clarification

@Rey thank you dear
you are the best
