Is There a Specific Name for Storage Site, Etc.?

Hi Guys,

I go on Winter Holiday to Africa.  But, I want to store my stuff in Beijing at a temporary site.

Is there such a place I can pay someone to do it?

I've never seen "self storage" type units in China.  I find this to be strange and wonder if I'm just missing them somehow.  Whenever I've mentioned the concept to my wife, she always seems to think the concept is silly.  Then again, I've got 3 or 4 boxes of stuff here which belong to a friend who just moved and couldn't fit everything into the car.

Yup, never seen those. Filing cabinets are surprisingly rare as well. And not too many birds or squirrels around here. You all know what that means...
