Stumbleupon/Reddit/Digg/etc equivalents in China?

Looking for China-specific 'post this story' mechanisms.

Hi,

I have a mirror of my main site in Beijing.

I have some localisation in Chinese, and hope to add more.

I support mobile browsing and slower connections to try to extend interest.

Now I'd like to plug into the Chinese way of doing things on the Net a tiny little bit more, replacing my western 'Digg'/'Slashdot'/etc discussion links with some Chinese equivalents.

Are there any?

What would be easiest for me is if there are any which support the:

http://example.cn/submit?url=#*$!

format. Again, are there any well-known ones?

China has no StumbleUpon or Digg?

I'm astonished!
