"The stomach occasionally feels uncomfortable, but hasn't been diagnosed with gastritis, so I rarely take antacid medication."
"Do you have chronic diarrhea, steatorrhea? Or any issues with the pancreas, liver, or gallbladder?"
"None."
"In gardening, do you specifically grow flowers or vegetables? What fertilizer do you use? Is the watercolor paint you use professional grade or children's grade? Do you have any special brand or color preferences?" Yang Ping's questions once again veer towards seemingly unrelated details.
Ms. Lin is a bit puzzled but still answers: "I mainly grow succulents and foliage plants, using ordinary compound fertilizer and nutrient soil. The watercolor is professional-grade Winsor & Newton. Colors? I use cobalt blue and cadmium red quite often, for painting the sky and sunset."
Cobalt blue, cadmium red? A sharp light flashes in Yang Ping's eyes, a "thread" emerges, and Yang Ping keenly grasps it.
