It tells the story of Chen Yan, a modern medical student who accidentally traveled to Chang'an in the prosperous Tang Dynasty. In this era of great splendor but crisis, he relied on modern medical knowledge and traditional Chinese medicine wisdom to start a medical legend that spans a thousand years. From the market turmoil in the east and west cities to the undercurrent of the banquet at the Ministry of Civil Affairs, from the warm promise of the first snow in Yangzhou to the difficult years of avoiding disasters on the island, the relationship between Chen Yan and Shen Qinghe gradually heated up in life and death tests. The two not only had to fight against the pursuit of Li Linfu's gang members, but also dealt with the plague sweeping Chang'an, and they also needed to find a balance in the collision between traditional medicine and modern knowledge. Hope you all like it.
