Liu Guodong and Yang Sen handled each sample cautiously.
"The fiber testing results are out; it's colored cotton."
"Colored cotton? This stuff isn't cheap."
Old Bai bought a set of colored cotton underwear during the New Year, costing several hundred yuan.

Soil from each location has different characteristics and components, and the soil in North Mountain of Haizhou City is a kind of clay, which can be used to make bricks and tiles.
"North Mountain..."
Lu Chuan had never been there, but Old Bai was familiar with the place.
