Why is the original rice pulp written in other places of the napkin, and the wood pulp written in Pinduoduo?

Pinduoduo sells all kinds of wood pulp paper. It turns out that the rice pulp written elsewhere in the napkin and the wood pulp written by Pinduoduo are all due to the wood pulp paper sold in Pinduoduo. Primary wood pulp refers to the pulp of completely natural wood, which is the highest quality pulp in the roll paper and usually has a higher price. Paper towels are mostly made of wood pulp, with low production cost and relatively mature channels.
