Qianzhitang was established in the late Ming Dynasty. According to the business directory of the old store published in the tenth year of Emperor Qianlong's reign in the Qing Dynasty (1744), it operated 15 categories and 624 types of finished medicines at that time, and also had the business of processing, preparing and wholesale of medicinal pieces. In the seventh year of Emperor Guangxu's reign, Wu Aiting took over Qianzhitang. Wu once worked in the Imperial Hospital, so some of the products were sold to the Imperial Pharmacy, some to large and small pharmacies in the city, and also to North China, Northeast China and along the Beijing-Baotou Railway. Wu Aiting asked Wang Zifeng to be the shopkeeper. Wang Zifeng was smart and capable, and his business was booming. During the Boxer Rebellion in 1900, Wang Zifeng bought precious medicinal materials from rich people at a low price. After the war, prices stabilized and Qianzhitang made a lot of money. Later, Wang Zifeng and Wu Aiting had a conflict, and Wang Zifeng left and raised funds to open Qingrentang Shenrongzhuang outside Chongwenmen. After Wang Zifeng left, Qianzhitang asked Wu Shouchen to take care of it. Wu Shouchen was also very good at business. In 1915, he opened Nanshantang Pharmacy in the south of Zhushikou, and later opened Qihuitang Pharmacy in Fuchengmen Street. Qianzhitang's main varieties include Huoluodan, Shuluodan, Sanhuangbao wax pills, tiger bone wine, tiger bone paste, etc. The special variety of Beijing-made Pinellia ternata is sold nationwide through Anguo Medicine Market. Since the late Qing Dynasty and the Republic of China, Qianzhitang's business scope has included back-counter wholesale and Mongolian and Tibetan medicine counters in addition to stores, and has trained Mongolian and Tibetan language personnel to receive customers. Qianzhitang's Chinese medicine is very popular among patients because of its low cost, low price and good efficacy. Later, Wu Zhensheng opened some branches one after another, making Qianzhitang gradually develop into a joint store of more than 20 stores. After liberation, due to the state's attention and support for Qianzhitang's time-honored brand, Qianzhitang's pharmacy business has become increasingly prosperous, especially maintaining its business characteristics of mainly selling decoction pieces. During the planned economy period, medicines, like other commodities, often suffered from shortages of certain finished medicines (or pieces of medicine). Qianzhitang was famous in Beijing for its complete range of pieces of medicine, and it became a consensus among Beijingers to go to Qianzhitang to buy herbal medicine. In the 1980s, Qianzhitang Pharmacy became the exclusive supply point for the Municipal Medicinal Materials Company to supply special goods to the central government and foreign guests of the embassy. The business scope and varieties have increased, and it has gradually developed into a large pharmacy with services such as Chinese patent medicines, Chinese medicine pieces, and processing of supplied materials. By 1990, Qianzhitang had more than 2,000 varieties of products. (No pictures yet, welcome to provide.) (No pictures yet, welcome to provide.)
