Chu Qingzhi looked at the paper in her hands, pondered for a while, then left the workshop and headed towards the store in the county that sold fish bladder glue and pigskin glue.
She hadn't thought of this before. For packaging, the paper needed to be glued together, but in ancient times, all glues were edible, so just buying some would do.
The shop assistant greeted her warmly, "Miss, what would you like to buy?"
Chu Qingzhi glanced around the shop and asked, "Do you have fish bladder glue and pigskin glue?"
"Yes," the assistant quickly retrieved both types of glue and placed them on the counter. "Here, Miss, these just arrived and are very fresh."
There wasn't much difference in appearance between the two types of glue. Chu Qingzhi inquired, "Which one is more expensive?"
The shop assistant pushed the jar containing the fish bladder glue towards Chu Qingzhi. "Fish bladder glue is harder to produce, so it's more expensive."
