Acupuncture

"I went to see the doctor for this, and the doctor prescribed some medicine for me. I can sleep for a few more hours now, but my head still hurts."

At this point, Old Master Lu was a little nervous. "Don't tell me I have cancer?"

Xia Wan comforted him. "Don't worry, Grandpa Lu. Your body is fine. The headache is just because you've been worried about a lot of things recently. I suggest you let go.

"I'll prescribe some medicinal dishes for you and give you the method to make them. I'll give them to your servant later and ask her to make a meal for you tomorrow.

"Also, if you trust me, I can help you with acupuncture."

Old Master Lu's eyes were filled with shock. "You know acupuncture?

"How come I've never seen your grandfather perform acupuncture? Did your grandfather learn this by himself after he returned home from the army?"

Xia Wan felt guilty for a moment. Her grandfather really didn't know acupuncture.
