My first lamp project - Antique Chinese Vase Lamp

This was one of my first lamp refurbishing projects. I rewired it and replaced the shade. The original wiring was cloth covered, so I replaced it with similiar. I'm guessing 1900 to 1920's??? When I took it apart the bottom is stamped in big black capital letters "CHINA" plus a paper stamp with a chinese character and then a red stamp on the porcelain itself with another series of chinese characters. Any information would be appreciated!
