internet in china (from Longmen Grottoes)

Hi there.
I'm in Longmen Grottoes in Luoyang.
it's world heritage place.
as you can see...just amazing place.

well internet in china is not internet, if you heard or not, it's intranet.
In china there's "Great FireWall"
100000 people in department of internet(government) pay attention to site now you are visit. And if it's not good for country, it doesn't connect.

I heard it while I'm traveling, it's like unbelieveable.
but I"m always having trouble with internet.
and 100000 people is a few % of full of chinese population.
so maybe true.

do you believe " Great Fire Wall"?
