Where can I find a place to sell clothes dyes in Lin 'an?

There is a jewelry store diagonally opposite the clove garden in Shijing Street. There is no signboard. Go there and ask if there is. I guess it's a little difficult to find dyes. If you dye it yourself, the color fastness is not high. There are some small dyehouses behind hangzhou east railway station Commodity Market, which can be taken to dye. To put it bluntly, there are dyes, and then they are boiled in a pot and then fished out, but their dyes are better. And dyeing this depends on the fabric, pure cotton will shrink when it encounters high temperature.
