Agricultural experts and sci-tech assistants have also joined some livestreaming sessions, teaching techniques step by step and solving farmers' problems.

This year, Mingguang launched 121 short videos on theoretical lectures, garnering 620,000 views. The city also livestreamed over 180 theoretical lectures, each of which attracted more than 1,000 views.

In early 2020, Du Bo crafted a vibrant story of cultural tourism revitalization in Northeast China, as she created a short video on epidemic prevention in the local dialect.

As the video garnered 750,000 views, Du, who was then director of the Culture and Tourism Bureau in Tahe county, Heilongjiang province, encountered the powerful reach of new media for the first time.

"The success inspired me to form my own new media team," she said."In my spare time, we filmed short videos or livestreamed to promote the icy landscapes, forest ecology and ethnic culture of Tahe."

In early 2023, when temperatures in the county hit a harsh — 20 C, Du donned traditional Oroqen attire to film a short video in a birch forest, titled White Deer Fairy. It went viral overnight.

"Our endeavor coincided with the 70th anniversary of the Oroqen people settling down since they moved out of the mountains," she said. "We went to see their ethnic costumes and cultural products, and those were exquisite. After getting the owner's consent, I borrowed the costumes for filming."

As the director of the tourism bureau, Du's job was to promote local tourism resources. "I not only promoted tourism, but also planned and built a large number of scenic routes and cultural projects each year," she said.

In 2024, Du became deputy director of the Enterprise Investment and Service Bureau of Hulan district in Harbin, the capital of Heilongjiang. However, her efforts to promote local tourism and economic development continued.

Du and her team have released more than 1,000 videos to date, with total views exceeding 4 billion and the number of followers across all platforms reaching over 2 million.
