Rear brake hose install....

Nice but it does not apply to most Chiners frames. They usually come with a full length housing. So you push from the rear till it comes out in the front.
That's when everything works fine 

Haha, thats the part of the build I'm not looking froward to when my 062 arrives, sounds like some frames are a real pain to install on 

My 062 is a huge pain in the ass. I have an early version. Hopefully they updated the way the hose exits the frame from behind the head tube.

my new trick that i wish i knew ages ago....

Plug all holes except for two ends then use vacuum cleaner to suck through a piece of string
tie string to hose and pull through
