Chapter 01
The Human Question
Memory loss rarely happens to one person alone. When someone begins to forget, the people around them start to remember on their behalf: the appointments, the medicine, the names of the grandchildren. Memory Guardians is about that quieter, shared side of Alzheimer’s disease.
Around 51 million people worldwide live with Alzheimer’s disease, and about 10 million of them are in China.1. Figures from the condensed edition of the 2024 China Alzheimer’s Disease Blue Book, as cited in the School of Television’s article about the film. They have not been checked against the Blue Book itself for this page. We began with those numbers and then tried to look past them, through real stories and the feelings they carry, so that viewers would understand the problem and want to support the people living with it.
Chapter 02
Finding the Story
The competition asked students to tell a story about China in a foreign language, for viewers abroad. We chose a social question that aging societies everywhere share, and looked for where China’s technology companies were trying to answer it.
Our research took us to the main exhibition of Beijing Science and Technology Week, where companies and research institutes showed what they were building, including a display about digital technology for the prevention and care of Alzheimer’s disease.

- 1. DisplayThe panel’s heading is about Alzheimer’s disease and digital technology for prevention and control.
- 2. On screenA life-size digital presenter invites visitors to ask questions about Alzheimer’s disease.
- 3. SubtitlesEnglish subtitles above Chinese: the film was made for viewers outside China.
“If it weren’t for this competition, I probably would never have known how many technology companies are working on public welfare and accessibility, taking on social responsibility through digital means.”
Chapter 03
Technology and Empathy
Our way into the subject was a small game called Building 6, Room 301, adapted by Tencent. The film looks at what it can do to teach the public about Alzheimer’s disease. On screen, the player is given ordinary tasks, the kind a person with memory loss can struggle to keep track of, such as taking the second dose of the day’s medicine at one o’clock.
Through staged, animated scenarios, the film asks how one of Tencent’s large language models might help older people and patients hold on to what they are losing, and help their families understand what is happening. We also interviewed people about the game’s effect.

The Film
The film moves between interviews, animated scenarios, screen recordings of AI tools and footage from the exhibition at Shougang Park. We filmed at the exhibition, in interviews indoors and out, and in a recording studio.

Making the film changed what I think technology stories are about. I went looking for products and found people: the ones who decided a game could teach empathy, the ones who sat down with us for interviews, and the families all of it is for.
It also taught me that telling a story in a second language takes more than an accurate translation. The film had to make a viewer who had never thought about Chinese families, or Chinese technology companies, care about both.
“It is because people keep speaking up for groups that society overlooks, sowing seeds of public good as best they can, that more people come to care, and society becomes warmer and more inclusive.”
The guardians in the title are not the machines. They are the people who decide what the machines are for.
