Who is the producer of teapot, Yu Ting?

You should be clear about the premise of the old pot. Now most people think that teapot has only appeared in recent years. Asking the name will make you look up the title, but you can't find a folk artist, so Cheng Shouzhen and Feng Guilin have become ordinary folk artists. To tell the truth, there are only a few masters who can reach the level of these folk artists now. Don't talk to me about flaps and needles. If you don't explain, everyone understands.
