Wujiadong Hospital was robbed and Master Wu died suddenly in prison. The reason behind this is that Dragon's Blood, an important medicinal material in the military plaster prepared by Wujiadong Hospital, was framed as a fake medicine. Du encouraged Shen to report Wu Weiwen. Wu Shu fell on the written pledge to fulfill a military order with ulterior motives. Although it was framed, it happened that a small bag of dragon blood ruined the Wu family.
On the basis of the historical facts of the Wu family in Anwubao, Jingyang County, Shaanxi Province, Yuet Wah tells the story that Zhou Ying, played by Sun Li, unexpectedly became a grandmother of the Wu family, fell into a complex conflict of interests for no reason, and finally solved many problems with unique wisdom and perseverance, casting a legendary businesswoman saint in the late Qing Dynasty.
