It is understood that the jadeite polishing in Shijiazhuang can be found in all districts and counties of Shijiazhuang, such as Chang 'an District, qiaoxi district and so on.

When jadeite is polished, firstly, the substance on the surface is cleaned with a soft brush, which is beneficial to better coloring. Then, soak in clear water for a period of time to let the jadeite absorb water. After washing, dry it with paper towels and let it stand in the shade for a few days.

The first is polishing, that is, coating a layer of polishing powder on the surface of the carved jade ornaments, and then grinding off all the burrs on the surface with oilstone or sandpaper.
