       28 . The rack module of  claim 21 , wherein a cross section of the rack module has a triangular shape. 
   
   
       29 . The rack module of  claim 21 , wherein a cross section of the rack module has a circular shape. 
   
   
       30 . A furniture assembly comprising:
 a first containing module having a frame defining a containing room, and including a plurality of convex-concave elements on an exterior surface of the frame of the first containing module, wherein a cross section of each convex-concave element has a triangular shape; and   a second containing module having a frame defining a containing room, and including a plurality of convex-concave elements on an exterior surface of the frame of the second containing module, wherein a cross section of each convex-concave element has a triangular shape,   wherein the first containing module and the second containing module combine into a furniture assembly by mating the convex-concave elements.   
   
   
       31 . The furniture assembly of  claim 30 , wherein cross sections of the first and the second modules have rectangular shapes. 
   
   
       32 . The furniture assembly of  claim 31 , wherein the convex-concave elements formed on a edge of the first containing module combine with the convex-concave elements formed on a edge of the second containing module. 
   
   
       33 . The furniture assembly of  claim 32 , wherein the convex-concave elements formed on a face of the first containing module combine with the convex-concave elements formed on a face of the second containing module. 
   
   
       34 . The furniture assembly of  claim 30 , including a fixing member, wherein the fixing member fixes the convex-concave elements of the first containing module and the convex-concave elements of the second containing module in a mating orientation. 
   
   
       35 . The furniture assembly of  claim 34 , wherein the fixing member includes:
 a first inserting part contacting an interior surface of the first containing module;   a second inserting part contacting an interior surface of the second containing module; and   a connecting part which connects the first inserting part and the second inserting part.   
   
   
       36 . The furniture assembly of  claim 35 , wherein a distance between the first inserting part and the second inserting part is variable. 
   
   
       37 . The furniture assembly of  claim 30 , wherein linear grooves are formed on interior surfaces of the first and the second containing module.
