Hi baijianpeng, and welcome to Tikiwiki Community
You can try yourself to produce that effect playing with categories and permisions to see categorized objects, etc.
Read documentation about it:
Or manually applying permissions to pages (you can do that for sure), but it will be time consuming on a page by page basis.
Hope it helps.
In order to add features, please add your "wish" on http://dev.tikiwiki.org , and consider requesting a Consultant to do it for you, if it takes too long for you to have that wish translated into reality, if you can't get to produce that desired effect with the current features.
