"By the way, I heard from Wei Jun that you are acting as the agent of Nanshan Pharmaceutical Company."
"Yes," Pan Jiayou replied.
"Are the Primordial Spirit Soup sales alright?"
"They are good," Pan Jiayou said. "The supply can't keep up with the demand. It's mainly because of the corresponding word-of-mouth. "The people who have used it all speak well of it."
"Why does that sound like advertisement copy?" Wang Yao asked with a chuckle. "Have you given it to your mother?"
"My mother has been taking it," Pan Jiayou replied. "She says she feels a little stronger after drinking it."
"Well, the Primordial Spirit Soup is mild in nature and has no toxic side effects," Wang Yao said. "It can be used as a tonic for a long time, but the main problem for your mother is that the flow of her Qi and blood are not smooth. Although this medicine is useful, only a little of it can be fully absorbed. That results in its poor efficacy."
