Suzhou small workshop mahogany erhu flat octagonal erhu Xu's erhu?

Dear friends, I have visited many erhu manufacturers many times and have some opinions on the production of erhu. The purpose of making erhu is not a workshop. The mass production of big brands leads to qualitative change, which is only a matter of high quality. Qin friends don't need to entangle the workshop. A good erhu lies in its application value, not the source of improving its value. I hope to see it for your reference!
