"The reason Minister Fu wants to devise a finer thread spindle is that silk can be made thinner, and some precious silk and brocade require extremely thin thread, which the general spindle cannot satisfy. But as I see it, there are very few people in the world who can use this spinning machine. Our Ministry of Industry should make it, but there is no need to promote it among the populace."
Zhao Hanzhang understood, "The fine thread spindle is sold to a targeted audience, and users are extremely few."
The craftsman nodded.
Fu Tinghan was about to speak but stopped.
Zhao Hanzhang knew what he wanted to say.
Currently, the areas for raising silkworms are mainly concentrated around Yu State, Jingzhou, and the Shu region, but in later generations, the well-known areas for raising silkworms are Jiangnan.
