"Centuries-old pharmacy goes down in history,
Healing people with brilliant efficacy.
Yi Zheng plaster spreads across the four seas,
The famous city's old shop takes the top spot."
The Legend of "Ju Jing Liu Xiang"
In 1712, Chen Pengnian, the Governor of Water Transport, suffered from severe joint pain. After being cured by our paste, he was struck by its unique herbal aroma. Inspired by the ancient legend of the "Orange Well" saving people from plague, he gifted us the plaque.
The 200-Year War on Fakes
For over two centuries, our fame attracted countless imitators. In 1869 (Tongzhi Year 8), the 7th generation master Tang Mu petitioned six levels of government.
This stele, now a protected cultural relic, stands as the "First Anti-Counterfeiting Stele in China," a permanent guardian of our authenticity.
The Heroine of the Tang Family
The Tang spirit extends beyond medicine. Tang Ruzhen, the 8th generation granddaughter, was a woman of extraordinary courage.
Inspired by Sun Yat-sen's call for women's rights, she donated over 50 mu (8+ acres) of her personal land to establish the Zhenjiang Women's Vocational School in 1927.
The Face That Guaranteed Quality
On the busy Wutiao Street, fakes were rampant. In 1922, the shop was officially registered as "Tang Lao Yi Zheng Zhai". But the ultimate seal of trust came in 1930.
This portrait guaranteed the authentic 80-herb formula. During the 1966 industrial consolidation, the formula was drastically cut.
Our global journey isn't new; it began over 140 years ago. On February 16, 1879 (Guangxu Year 5), an advertisement in the Shen Bao (Shanghai News) announced our Shanghai branch.
"No goods leave the door if ingredients are missing;
Genuine goods at a fair price, no second price."
