Tianfuhao Braised Pork Shop was founded in the third year of Emperor Qianlong's reign in the Qing Dynasty (1738). At that time, Shandong suffered from a severe drought and no crops were harvested. Liu Fengxiang, a native of Ye County, Shandong, led his grandson Liu Diming to escape the famine and come to Beijing to make a living. They opened a braised pork shop at the northeast corner of Xidan Archway and named it "Tianfuhao", which means a blessing from heaven. The braised pork elbows made by Tianfuhao are crispy and delicious, with excellent quality, attracting everyone from high-ranking officials to ordinary people to patronize. Empress Dowager Cixi also praised it after tasting it, and gave it a "Tianfuhao waist badge", stipulating that Tianfuhao would deliver braised pork elbows to the palace every day with a fixed amount of waist badges. Since then, "Tianfuhao Braised Pork Elbows" have become tributes and their reputation has been boosted. In 1993, "Tianfuhao" was rated as a "Chinese time-honored brand". So far, "Tianfuhao" has been passed down for eight generations. In the historical changes of more than 270 years, its braised pork elbows and other products have always maintained superior quality. The skill of making Tianfuhao braised pork elbow was formed by the Liu family's grandfather and grandson through repeated research in the business. The method of making braised pork elbow is unique and different from others. Tianfuhao braised pork elbow is made of fine materials. After being made, it is fat but not greasy, lean but not dry, and the skin is not greasy. It has a rich and mellow aroma. Since the beginning of the 21st century, due to the heavy burden of old enterprises, shortage of funds and talents, small production sites, aging of skilled workers, outflow of skilled talents and other reasons, the inheritance of Tianfuhao braised pork elbow making skills has become increasingly difficult and there is a lack of successors. To change this situation, effective protection measures must be formulated as soon as possible.
