"I know, you've already told me the symptoms and the time they occurred, but I want to ask, the day before or maybe two days before the symptoms appeared, did the elder visit any place, or eat something from outside? Do you have any recollection of that?"
"My mother, she usually just stays at home, tending to her plants, spending most of her time sitting in the yard, soaking up the sun. She rarely goes out."
"But son, now that I think about it, she did go to a temple fair that one time. I went with your Aunt Guizhi to the fair, and after coming back from the fair, that reaction occurred. I haven't been since then."
"You mean, you went to the temple fair on the east side of the town? Ah, I didn't pay attention to that; I'm always so busy with work and hadn't noticed this point. What's the matter, Dr. Liu?"
"Madam, please try to remember. At the fair held in that town, did you eat or drink anything? Did you have any contact with other people? Do you remember anything about that?"
