Not long ago, a cultural feature film with only 15 minutes per episode attracted many audiences' interest. In the feature film, Shan Jixiang, president of the Chinese Cultural Heritage Society and president of the Dongcheng Cultural Development Research Institute in Beijing, walked through Dongcheng District of Beijing with Professor Zhang Jin of Tsinghua University at a high temperature of about 40 degrees Celsius, talking about many cultural heritages in Dongcheng District. A Beijing audience said that although he was born and raised in Dongcheng, he did not know much about many cultural relics. After watching this TV film called "Old Man Going East", I found that so many cultural heritages are around me. Why did Shan Jixiang, who once served as the director of the National Cutural Heritage Administration and the president of the Palace Museum, choose to focus on a city and explain the obscure cultural heritage around many people? How can our heritage protection work take root? On a sunny spring afternoon, with many questions, our reporter interviewed Shan Jixiang. He talked about the cultural transmission in Dongcheng District in recent years, and how to let the charm of cultural heritage "fly into the homes of ordinary people", and then opened the conversation box. Shan Jixiang is from the old Dongcheng. He recalled that he lived near the former Longxugou before he was 6 years old, lived in the back street of the Art Museum from 1971 to 1978, and lived in Dongcheng District after returning from studying abroad. In the past 20 years, he has been living in a house in Dongcheng District. "I have a deep feeling for Dongcheng District. It can be said that Dongcheng District is my hometown, where my childhood, youth and old age all live. Here, through the streets and lanes, there is culture everywhere, and I am thinking about how to publicize the cultural charm of Dongcheng District." Shan Jixiang said. When talking about the East City, Shan Jixiang always talks. For example, the water plant in the Qing Dynasty was the first water plant in Beijing's history. Here you can tell us where Beijing's drinking water came from; When the founding ceremony of the People's Republic of China was held, the flagpole of the national flag on the Tiananmen Square was made of the water pipe of the water plant; In the ancient observatory, we can watch the celestial phenomena at night and see our Tiangong Space Station; The Confucius Temple and the Imperial College Museum reflect the Chinese tradition of attaching importance to knowledge and education... In February 2021, the Beijing Dongcheng Cultural Development Research Institute was inaugurated in Beijing, and Shan Jixiang was appointed as the president. At the founding ceremony, He expressed his sincere emotion: "I have traveled through many countries and cities, such as Dongcheng District, which has three world cultural heritages, and integrates the royal family, Confucianism, traditional Chinese culture, guild halls and other diverse cultures represented by the Forbidden City, the Temple of Heaven, the Lama Temple, the Confucian Temple, the Confucius Temple, the Imperial Academy, the Temple of the Earth, the Ming City Wall, the front door archery tower, and the Yongdingmen City Tower, which collectively reflects the charm of the ancient capital imperial city culture and folk culture. It can be said that it is the only place that is worthy of the name of" Capital Culture " A total of 9 episodes of "Old Man Walking in the East City" is the latest work of Beijing Dongcheng Cultural Development Research Institute.
