Material Story: In 2007, during road construction in Dingshu Town (near Huanglong Mountain No.3 Slope, 50 meters from Dashi Pond), a rare purple clay deposit with a red hue like blood was discovered. The thickest part was under 15cm, with only about 3 tons of total clay found. Local miners regarded it as "Dragon's Blood," believed to bring good fortune and wealth.
