Qin Xueru quickly noticed Su Yayan's strange expression. She frowned and asked with concern, "What's wrong? Did something happen?"
Su Yayan snapped out of her trance and said anxiously, "Aunt Qin, please extend your hand."
"My hand?" Although Qin Xueru was confused, she still did as she was told.
Su Yayan felt her pulse, and the uncertainty in her eyes was quickly replaced by pure excitement.
"What happened? Yanyan, why are you holding your aunt's hand?"
"I'm taking my aunt's pulse!"
"Taking her pulse?" Cheng Xiuqin frowned." What do you mean by taking her pulse?"
"Taking a pulse is by feeling someone's pulse on the wrist."
When Su Yayan said this, Qin Xueru and Cheng Xiuqin both looked surprised.
In this era, most herbs were extinct, and Chinese medicine only existed in the scientific literature. Few people knew about it.
