Chinese type 56-1 how-to

Is there a guide somewhere to show how to: 1. remove the bayonet from a type 56-1 2. Check if the muzzle is changeable 3. Change the muzzle 4. Disassemble the handguard

Bonus if there's one to showcase the full disassembly 😁

Edit: added some pictures to help understand what I'm talking about
