In the modern sense, industrial and commercial advertising in my country has gradually emerged since the middle of the Qing Dynasty. At that time, some drug stores often covered medicine packages with a woodblock-printed "manual sheet" in order to expand their publicity effect. The old manual is also a kind of instruction manual that introduces the properties, efficacy, and usage of the medicine. With the advancement of printing technology, the manual also has the properties of a kind of credibility guarantee or "anti-counterfeiting" label.

Since ancient times, there have been many people who deceived the world and stole the name. Helpless merchants moved their advertisements into this leaflet to advertise to the public. Instructions have become an important way to win the trust of the people.

In the early years, Tianjin's Tianhou Temple Temple Market was bustling with activity, and the bright eye drops in Chunyong Hall in the temple were a treasure. Chunyongtang's manuals are printed with its own trademark pattern in the advertisement, which is rare among old manuals. The advertising significance is highlighted, and it has a clear and effective publicity significance.
