Because of the Great Firewall of China, the Chinese internet has developed into a separate ecosystem that is structurally different from much of the rest of the online world. If you try to explain Red Note to people outside the Sinophone world, it is actually hard to find one exact word for it. It is not simply a social media platform, and it is not a remake of Instagram, Reddit, or X. Red Note is a community that mainly uses Chinese and centers on everyday experience. People share product reviews, life records, practical advice, and emotional reflections, and the platform also has shopping functions.
Red Note was founded in Shanghai in 2013. At the beginning, it served Chinese outbound travelers and offered overseas shopping guides and product recommendations. Users recorded what they bought abroad and where it was cheaper. Between 2014 and 2015, Red Note began to experiment with e-commerce and tried to turn content into purchases. As the user base grew, Red Note gradually shifted from a tool to a community. Shopping experiences became life experiences. Product reviews extended into self-narration. Consumption became part of identity expression. The user group also expanded from Chinese people living or traveling abroad to the wider Sinophone world, and today it includes a small number of users who use other languages. By 2022, Red Note had reached about 200 million monthly active users in mainland China, and most users were between 18 and 35. After several rounds of funding, its valuation once rose to tens of billions of US dollars.
What gives Red Note its current status is its algorithmic system. Before Red Note, highly personalized matching algorithms were more common in streaming platforms, but Red Note brought this logic into a social platform. Small actions are recorded and used to predict what a user wants to see next. These actions include where a user is located, what they post about, how long they stay on certain posts, whether they finish a video, whether they open the comment section, whether they save content, and whether they repeatedly search for the same topic. The result is that your home feed is not about what is happening in the world. It is about what the algorithm thinks will keep you staying. The system strengthens the interests you have already shown and makes your digital environment look more and more like yourself. This recommendation model has attracted a large number of new users.
Red Note is therefore highly localized. The algorithm constantly adjusts what you see based on language, location, and user behavior. If your search is not very specific, the same keyword can lead to very different results for different groups. I once searched the same public event topic on different accounts and received two versions of reality that almost did not overlap.
As the algorithm became stronger and the user base grew quickly, Red Note gradually took on a role similar to a search engine. When people want to know whether a city is worth visiting, whether a major is worth studying, whether a restaurant is likely to be disappointing, or whether a medicine may have side effects, many people do not open Baidu or Google first. They search directly on Red Note.
The range of content on Red Note is broader than most people imagine. I once found a practical guide there on how to get from a remote Italian island to a nearby city after the last ferry of the day had stopped running. This also reflects a common saying that Chinese people have been to every corner of the world. I also found instructions on how to repair an old mechanical toy. Red Note does not provide one standard answer. It provides dense collections of personal experience. This kind of concrete and emotional narration can make information feel more trustworthy and closer to real decision-making.
In addition, follower count carries a relatively low weight in content distribution on Red Note, so even posts from new users can still be pushed by the system. Because its recommendation system is so strong, Red Note can also be unusually useful for quick interaction and practical problem-solving. If a user posts that their elderly mother is waiting alone at an airport in a certain city, that her phone may have run out of battery, and that the user is far away and cannot reach her, the post can be pushed within an hour to the home feeds of other users who are currently in the same airport. This can lead to successful help between strangers. In moments like this, the algorithm temporarily becomes a form of public coordination.
All of this has made Red Note function almost like the best search engine in contemporary China.
At the same time, Red Note has its own ideological leanings. For a long time, it has often been described as a lifestyle community for middle-class young women. This is because its earliest core users were mainly middle-class young women. Compared with more traditional social platforms, Red Note tends to be more consumerist and more elitist, but it is also more feminist. Chinese social platforms often show strong gender and class orientations. For example, Douyin, the Chinese version of TikTok, is often seen as representing lower-income markets. Red Note is one of the fastest-growing platforms in recent years, and the ideological tendencies it represents may be gaining strong influence in China.
So, where in the world is Red Note?
It exists within the online boundaries shaped by the Great Firewall of China. It exists in the evolution of a platform from a tool into an infrastructure. It exists in algorithmic mechanisms that divide reality into separate zones. It exists in a search practice where experiential knowledge can replace traditional web indexing. It also exists in an ideological atmosphere shaped by class and gender.
Instead of asking where Red Note is, we might ask: who is holding the world we live in, when information is no longer shaped mainly by publishers but by the structure of platforms？
