1. I also searched casually just now, only to find that there is a website dedicated to soft pottery training. Hehe, I advertised to others for free, and I will put the picture at the end. There should be many such training institutions. Please have a look and find out.
2. I see that there are many related tutorials. According to these tutorials, you can contact related soft pottery professionals, ask others for advice or learn from each other, and more professional ones can apply for apprenticeships. You can try them all.
3. I saw many wholesale and retail enterprises of soft pottery on Taobao or Alibaba. You can also follow suit and find a company with good qualifications as an apprentice. This is also a way.
Let go of what you want to do, work hard while you are young and enthusiastic. As long as you are willing to do it, there is no difficulty.
I sincerely hope I can help you, and I wish you good luck!
