Hello Fatemeh_vlp , and welcome to OpenStreetMap!             
      
In this changeset you added the mall's name to the landuse w1167428581, while the name of the mall is already added on the mall building w1167428601, therefore this changeset has been reverted by changeset 146492996.      
      
I would also like to mention a few other thing, if you are a member from a foreign iranian editing team editing in Iraq, please read what I said to your colleague here, when she edited the same landuse:
