"That black line on your child's gums is a clear sign of poisoning."
Li Xu spoke in a serious tone, pointing to the boy's gums. "Look for yourself. This distinct blue-black line is a classic sign of lead poisoning. That's why the 'normal' on the report is what's really problematic."
"Well..."
Zhang Yue Mei saw Li Xu's solemn expression, and the faint, yet jarring, black line on the edge of her son's gums suddenly seemed much more prominent.
She was torn.
She was more inclined to believe the results of the "scientific instruments," but she also felt what Li Xu said made some sense.
"I... I'll think about it some more."
In the end, Zhang Yue Mei didn't let Li Xu prescribe any medicine.
Holding her son, she left the clinic.
Back at home, her son, exhausted, fell into a deep sleep.
Zhang Yue Mei started preparing lunch.
As she cooked,
she couldn't stop thinking about what Li Xu had said.
