"Beijing is an attractive city with cultural richness," Lu says. "It's our slogan to see Beijing in our small courtyard. We hope to spread Chinese and Beijing culture based on our events and activities and turn our courtyard into a showcase of China's cultural confidence."

The documentary focuses on multiple topics pertinent to Beijing, including cultural heritage, ecological development, preservation of the old town and the construction of the international consumption center.

Bian Jian, deputy editor-in-chief of Beijing Radio and Television Station, says the production team held several planning meetings to finally choose the innovative micro-documentary filming method, as it's an innovative expression of the traditional documentary, which is recorded in a new media context using short videos.

"The 30-episode show visits all corners of Beijing, objectively showing the lives of people, the development of Beijing as a city and the spirit of the time in China, all from a micro perspective," Bian says.

"The documentary not only satisfies the rapid communication needs of modern society with its fragment-like format, but is a microscopic, historical image of Beijing in the new era," he says.

According to Xu Hejian, spokesman of Beijing municipal government, the documentary — showing Beijing's great achievements around the theme of "what kind of capital is being built and how to build the capital" — took two years to make.

"As the wheel of history is steadily moving forward, what has changed is the appearance of the city, while what remains unchanged is the unique heritage and essence of Beijing," Xu says.

Xu says that he hopes the audience will experience the coexistence of ancient and modern Beijing through the documentary, which will enable more people from different countries to better understand the city.

The documentary was launched on overseas media and social media platforms such as Facebook, Twitter, YouTube and TikTok.
