Loss of original geographical advantages. With the continuous urban construction and expansion in Beijing, many streets and buildings in the old city have undergone great changes, and the old restaurants have been forced to relocate or gradually lost their original geographic advantages and customer groups, while the emergence of new business districts and the gradual molding of new consumer concepts have also generated new challenges to the market position and business model of the old restaurants. Beijing is China's capital city and the center of the country's politics, culture, science and technology in various fields, and is also one of the cities with a long history and deep cultural heritage.
