China’s Xiaohongshu (Rednote) has seen an unprecedented influx of foreign “TikTok refugees” over the past week, giving rise to endless jokes. But behind this unexpected online migration lie some deeper themes—geopolitical tensions, a desire for cultural exchange, and the unexpected role of the fictional character Li Hua in bridging the divide.

Imagine you are Li Hua (李华), a Chinese senior high school student. You have a foreign friend, far away, in America. His name is John, and he has asked you for some insight into Chinese Spring Festival, for an upcoming essay has to write for the school newspaper. You need to write a reply to John, in which you explain more about the history of China’s New Year festival and the traditions surrounding its celebrations.

This is the kind of writing assignment many Chinese students have once encountered during their English writing exams in school during the Gaokao (高考), China’s National College Entrance Exams. The figure of ‘Li Hua’ has popped up on and off during these exams since at least 1995, when Li invited foreign friend ‘Peter’ to a picnic at Renmin Park.

Over the years, Li Hua has become somewhat of a cultural icon. A few months ago, Shangguan News (上观新闻) humorously speculated about his age, estimating that, since one exam mentioned his birth year as 1977, he should now be 47 years old—still a high school student, still helping foreign friends, and still introducing them to life in China.

Li Hua: the connector, the helper, the icon.

This week, however, Li Hua unexpectedly became a trending topic on social media—in a week that was already full of surprises.

With a TikTok ban looming in the US (delayed after briefly taking effect on Sunday), millions of American TikTok users began migrating to other platforms this month. The most notable one was the Chinese social media app Xiaohongshu (now also known as Rednote), which saw a massive influx of so-called “TikTok refugees” (Tiktok难民). The surge propelled Xiaohongshu to the #1 spot in app stores across the US and beyond.

This influx of some three million foreigners marked an unprecedented moment for a domestic Chinese app, and Xiaohongshu’s sudden international popularity has brought both challenges and beautiful moments. Beyond the geopolitical tension between the US and China, Chinese and American internet users spontaneously found common ground, creating unique connections and finding new friends.

While the TikTok/Xiaohongshu “honeymoon” may seem like just a humorous trend, it also reflects deeper, more complex themes.

 
✳️ National Security Threat or Anti-Chinese Witchhunt?
 

At its core, the “TikTok refugee” trend has sprung from geopolitical tensions, rivalry, and mutual distrust between the US and China.

TikTok is a wildly popular AI-powered short video app by Chinese company ByteDance, which also runs Douyin, the Chinese counterpart of the international TikTok app. TikTok has over 170 million users in the US alone.

A potential TikTok ban was first proposed in 2020, amid escalating US-China tensions. President Trump initiated the move, citing security and data concerns. In 2024, the debate resurfaced in global headlines when President Biden signed the “Protecting Americans from Foreign Adversary Controlled Applications Act,” giving ByteDance nine months to divest TikTok or face a US ban.

TikTok, however, has continuously insisted it is apolitical, does not accept political promotion, and has no political agenda. Its Singaporean CEO Shou Zi Chew maintains that ByteDance is a private business and “not an agent of China or any other country.”

🇺🇸 From Washington’s perspective, TikTok is viewed as a national and personal security threat. Officials fear the app could be used to spread propaganda or misinformation on behalf of the Chinese Communist Party.

🇨🇳 Beijing, meanwhile, criticizes the ban as an act of “bullying,” accusing the US of protectionism and attempting to undermine China’s most successful internet companies. They argue that the ban reflects America’s inability to compete with the success of Chinese digital products, labeling the scrutiny around TikTok as a “witch hunt.”

“This will eventually backfire on the US itself,” China’s Foreign Ministry spokesperson Wang Wenbin predicted in 2024.

Wang turned out to be quite right, in a way.

When it became clear in mid-January that the ban was likely to become a reality, American TikTok users grew increasingly frustrated and angry with their government. For many of these TikTok creators, the platform is not just a form of entertainment—it has become an essential part of their income. Some directly monetize their content through TikTok, while others use it to promote services or products, targeting audiences that other platforms like Facebook, Instagram, or X can no longer reach as effectively.

Initially, the mass migration of American users to Xiaohongshu was a symbolic protest against US policies. Users advocated for the right to choose their preferred social media, and voiced their frustration at how their favorite app had become a pawn in US-China geopolitical tensions. Rejecting the narrative that “data must be protected from the Chinese,” many pointed out that privacy concerns were equally valid for US-based platforms. As an act of playful political defiance, these users downloaded Xiaohongshu to demonstrate they didn’t fear the government’s warnings about Chinese data collection.

(If they had the option, by the way, they would have installed Douyin—the actual Chinese version of TikTok—but it is only available in Chinese app stores, whereas Xiaohongshu is accessible in international stores, so it was picked as ‘China’s version of TikTok.’)

Xiaohongshu is actually not the same as TikTok at all. Founded in 2013, Xiaohongshu (literal translation: Little Red Book) is a popular app with over 300 million users that combines lifestyle, travel, fashion, and cosmetics with e-commerce, user-generated content, and product reviews. Like TikTok, it offers personalized content recommendations and scrolling videos, but is otherwise different in types of engagement and being more text-based.

As a Chinese app primarily designed for a domestic audience, the sudden wave of foreign users caused significant disruption. Xiaohongshu must adhere to the guidelines of China’s Cyberspace Administration, which requires tight control over information flows. The unexpected influx of foreign users undoubtedly created challenges for the company, not only prompting them to implement translation tools but also recruiting English-speaking content moderators to manage the new streams of content. Foreigners addressing sensitive political issues soon found their accounts banned.

Of course, there is undeniable irony in Americans protesting government control by flocking to a Chinese app functioning within an internet system that is highly controlled by the government—a move that sparked quite some debate and criticism as well.

 
✳️ The Sino-American ‘Dear Li Hua’ Moment
 

While the initial hype around Xiaohongshu among TikTok users was political, the trend quickly shifted into a moment of cultural exchange. As American creators introduced themselves on the platform, Chinese users gave them a warm welcome, eager to practice their English and teach these foreign newcomers how to navigate the app.

Soon, discussions about language, culture, and societal differences between China and the US began to flourish. Before long, “TikTok refugees” and “Xiaohongshu natives” were collaborating on homework assignments, swapping recipes, and bonding through humor.

For instance, Chinese users jokingly asked the “TikTok refugees” to pay a “cat tax” for seeking refuge on their platform, which American users happily fulfilled by posting adorable cat photos. American users, in turn, joked about becoming best friends with their “Chinese spies,” playfully mocking their own government’s fears about Chinese data collection.

The newfound camaraderie sparked creativity, as users began generating humorous images celebrating the bond between American and Chinese netizens—like Ronald McDonald cooking with the Monkey King or the Terra Cotta Soldier embracing the Statue of Liberty. Later, some images even depicted the pair welcoming their first “baby.”

🇺🇸 At the same time, it became clear just how little Americans and Chinese truly know about each other. Many American users expressed surprise at the China they discovered through Xiaohongshu, which contrasted sharply with negative portrayals they’ve seen in the media. While some popular US narratives often paint Chinese citizens as “brainwashed” by their government, many TikTok users began to reflect on how their own perspectives had been shaped—or even “manipulated”—by their media and government.

🇨🇳 For Chinese users, the sudden interaction underscored their digital isolation. Over the past 15 years, China has developed its own tightly regulated digital ecosystem, with Western platforms like Facebook, Twitter, Instagram, and YouTube inaccessible in the mainland. While this system offers political and economic advantages, it has left many young Chinese people culturally hungry for direct interaction with foreigners—especially after years of reduced exchange caused by the pandemic, trade tensions, and bilateral estrangement. (Today, only some 1,100 American students are reportedly studying in China.)

The enthusiasm and eagerness displayed by American and Chinese Xiaohongshu users this week actually underscores the vacuum in cultural exchange between the two nations.

As a result of the Xiaohongshu migration, language-learning platform Duolingo reported a 216% rise in new US users learning Mandarin—a clear sign of growing interest in bridging the US-China divide.

Mourning the lack of intercultural communication and celebrating this unexpected moment of connection, Xiaohongshu users began jokingly asking Americans if they had ever received their “Li Hua letters.”

What started as some lighthearted remarks evolved into something much bigger as Chinese users dug up their old Gaokao exam papers and shared the letters they had written to their imaginary foreign friends years ago. These letters, often carefully stored in drawers or organizers, were posted with captions like, “Why didn’t you reply?” suggesting that Chinese students had been trying to reach out for years.

The story of ‘Li Hua’ and the replies he never received struck a chord with American Tiktok users. One user, Debrah.71, commented:
“It was the opposite for us in the USA. When I was in grade school, we did the same thing—we had foreign pen pals. But they did respond to our letters.”

Then, something extraordinary happened: Americans started replying to Li Hua.

One user, Douglas (@neonhotel), posted a heartfelt video of him writing a letter to Li Hua:

📝”Dear Li Hua, I’m sorry I didn’t get your letters. I understand you’ve been writing me for a long time, but now I’m here to reply. Hello, from your American friend. I hope you’re well. Life here is pretty normal—we go to work, hit the gym, eat dinner, watch TV. What about you? Please write back. I’m sorry I didn’t reply before, but I’m here now. Your friend, Douglas.”

Another user, Tess (@TessSaidThat), wrote:

📝”Dear Li Hua, I hope this letter finds you well. I’m so sorry my response is so late. My government never delivered your letters. Instead, they told me you didn’t want to be my friend. Now I know the truth, and I can’t wait to visit. Which city should I visit first? With love, Tess.”

Examples of Dear Li Hua letters.

Other replies echoed similar sentiments:

📝”Dear Li Hua, I’m sorry the world kept us apart.”

📝”I know we don’t speak the same language, but I understand you clearly. Your warmth and genuine kindness transcend every barrier.”

📝”Did you achieve your dreams? Are you still practicing English? We’re older now, but wherever we are, happiness is what matters most.”

These exchanges left hundreds of users—both Chinese and American, young and old, male and female—teary-eyed. In a way, it’s the emotional weight of the distance—represented by millions of unanswered letters—that resonated deeply with both “TikTok refugees” and “Xiaohongshu natives.”

The letters seemed to symbolize the gap that has long separated Chinese and American people, and the replies highlighted the unusual circumstances that brought these two online communities together. This moment of genuine cultural exchange made many realize how anti-Chinese, anti-American sentiments have dominated narratives for years, fostering misunderstandings.

On the Chinese side, many people expressed how emotional it was to see Li Hua’s letters finally receiving replies. Writing these letters had been a collective experience for generations of Chinese students, creating messages to imaginary foreign friends they never expected to meet.

Receiving a reply wasn’t just about connection; it was about being truly seen at a time when Chinese people often feel underrepresented or mischaracterized in global contexts. Some users even called the replies to the Li Hua letters a “historical moment.”

 
✳️ Unity in a Time of Digital Divide
 

Alongside its political and cultural dimensions, the TikTok/Xiaohongshu “honeymoon” also reveals much about China and its digital environment. The fact that TikTok, a product of a Chinese company, has had such a profound impact on the American online landscape—and that American users are now flocking to another Chinese app—showcases the strength of Chinese digital products and the growing “de-westernization” of social media.

Of course, in Chinese official media discourse, this aspect of the story has been positively highlighted. Chinese state media portrays the migration of US TikTok users to Xiaohongshu as a victory for China: not only does it emphasize China’s role as a digital superpower and supposed geopolitical “connector” amidst US-China tensions, but it also serves as a way of mocking US authorities for the “witch hunt” against TikTok, suggesting that their actions have ultimately backfired—a win-win for China.

The Chinese Communist Party’s Publicity Department even made a tongue-in-cheek remark about Xiaohongshu’s sudden popularity among foreign users. The Weibo account of the propaganda app Study Xi, Strong Country, dedicated to promote Party history and Xi Jinping’s work, playfully suggested that if Americans are using a Chinese social media app today, they might be studying Xi Jinping Thought tomorrow, writing: “We warmly invite all friends, foreign and Chinese, new and old, to download the ‘Big Red Book’ app so we can study and make progress together!”

Perhaps the most positive takeaway from the TikTok/Xiaohongshu trend—regardless of how many American users remain on the app now that the TikTok ban has been delayed—is that it demonstrates the power of digital platforms to create new, transnational communities. It’s unfortunate that censorship, a TikTok ban, and the fragmentation of global social media triggered this moment, but it has opened a rare opportunity to build bridges across countries and platforms.

The “Dear Li Hua” letters are not just personal exchanges; they are part of a larger movement where digital tools are reshaping how people form relationships and challenge preconceived notions of others outside geopolitical contexts. Most importantly, it has shown Chinese and American social media users how confined they’ve been to their own bubbles, isolated on their own islands. An AI-powered social media app in the digital era became the unexpected medium for them to share kind words, have a laugh, exchange letters, and see each other for what they truly are: just humans.

As millions of Americans flock back to TikTok today, things will not be the same as before. They now know they have a friend in China called Li Hua.
