Porcelain field of the official kiln now also official kiln and folk kiln called way

Now there is basically no official kiln and folk kiln points, especially in the last 30 years, the vast majority of porcelain furnishings are out of folk artists, in a sense that this is also considered a "folk kiln" porcelain, the true meaning of the official kiln porcelain is no longer available, so there is no official kiln and folk kiln points. Thank you
