General materials, that is, crude scrolls (that is, framed), can be bought in specialized calligraphy and painting shops in Four Treasures of the Study, usually in 35 yuan.
If you want a better material, you can buy a banner Xuan paper of about 10 yuan from a calligraphy and painting shop in Four Treasures of the Study, and then ask a Four Treasures of the Study shop or a mounting shop to mount it into a shaft (generally, write on the Xuan paper first, and then mount it). Mounting is divided into machine mounting and manual mounting. Generally speaking, machine mounting is five yuan cheaper than manual mounting, but in some places it is just the opposite, but the difference is five yuan, so the four-foot banner rice paper is 65438.
Note: Generally, manual mounting is more delicate. You can ask the framer to wax the back, which will be smoother. Manual installation is slower than machine installation, but it can be left uncovered. Generally, more expensive works are mounted by hand.
