Raised marks on bottom of vase

[Barbz216]

Hello.  I'm new to this, so please be patient with me!  I have a large 'oriental' vase (standing 24" / 61cms tall).  It has peacocks, pink and orange flowers and black/v dark blue leaves on.  It is not highly glazed.  It has raised characters on its bottom that I would like identifying.  Can anyone help?  Thanks
