Wang Shizhen was stunned.
He never expected Du Heng to ask such a question. He also never expected Du Heng to have some knowledge about four seasons nourishment. As for Du Heng's sudden question, he didn't know how to answer. To make these dishes, he would first buy books, research information, and then slowly experiment on his own. After making them, he would try them himself first. If the taste wasn't good, he would definitely scrap it. As for the effects, he couldn't tell either. So, while he might have some basic cooking skills, for dietary therapy, he was still in the phase of knowing what to do but not why; he really couldn't answer Du Heng's question. Because he hadn't studied the medicinal properties of these ingredients. For diners and tourists, he could bluff his way through. But with Du Heng, mere bluffing wouldn't work; rambling on would likely make him lose even more face.
