@toloco, I didn’t fix it dude, hinges is glued to the screen as lid is very thing. I contacted the seller and he proposed hinges for 30$, but I believe it is impossible to fix.
So, in the end, as I worried about in early stage I still have one hinge working, so I stopped closing the lid (except 2 times for transportation purpose) and use is more like desktop with ability to take it in bed (as it still lightweight).
P.S. As from January 2020 I have bought HP ENVY 360 convertable laptop so I don’t have this problems any more. I gave CHUWI to my aunt to use.
