Way before Firefox AdBlock Plus was invented, we of the Internet surfing tribe trained our eyes to bypass blinking buttons of spam, taught our brain to disregard advertisements' riot of colors. We went, and we still go, for what we came for on a page. Some black or blue, on white or gray, with some tastefully done, color coordinated adverts lurking on the sidelines. If we are on a comic strip site, where there is a friskier mood in the air, there will probably be a modest flash ad of a computer game. Blinking red on black? Why are you on a pr0n site while at work?
This approach will get you nowhere on a Chinese site. You can spend all the time you want getting through meaningless little text links to the left, and modest go-nowhere buttons to the right. But HOWCANYOUNOTSEEIT!!!?? This, yes, the honking huge green 3D button, that is dancing right in front of you, blinking orange text and jumping up and down. The one surrounded by useful information typed in glittering, swirling, sparkling pink. Right under the running banner, exonerating the virtues of rising early, drinking milk and buying Brandname cellphones, in gold upon scarlet. Oh, you thought it was spam. Your brain refused to acknowledge it... You tried to get your cursor around it... Well, good luck with that. This is the magic button that opens a new tab with more dancing blinking shit, from where you go to another one, and there be your info.
Then you have to go back to your browser, and close all those bloody windows manually. I remember sharing a computer with some girl back in China, I think she invited me over. I showed her something in English, and then went further down the linky-link path. Naturally, my info just flows with it. No need to open everything in a new window. How appalled she was that I can't retrieve pages from half an hour ago without googling for them. And even the fact it took five seconds couldn't placate her. Really those guys are the Internet magpies.
