Where can I learn to be a tailor in Zigong?

You can go to a vocational and technical school. However, if you want to study a major, but apply to a correspondence school in other places, I feel that Zigong has no special major. If you just study technology, not design, then go to a better shop and find a master to learn. I feel that there is a shop in Dunganba with exquisite workmanship. You can try it.

If you want to learn design, go somewhere else. You need professionals to teach it.
