Do you want to learn darning techniques or go to Luoyang to learn darning? The teacher has a shop and is very experienced in doing work. I learned it from him last summer vacation. Teacher Zhang teaches really well. She has teaching experience and is easy to understand, so it is easy and effortless to learn. It's been almost a year since I opened the store, and I've done a lot of work. My clients praised me for my good work, and they were very satisfied.
