• A Chinese social media app called Xiaohongshu is one of the biggest winners from a looming TikTok ban.
• It's so popular in the US that Chinese users have started a new hashtag to welcome Americans.
• The cultural exchange frenzy has birthed posts of people asking for help with English homework, among other requests.

A Chinese social media platform has grown so popular in the US that it's this week's most downloaded iPhone app — and it's become the site of a sudden East-Meets-West cultural exchange.

Xiaohongshu, also known as RedNote, hit the top spot on the US Apple store's ranking this week as a divest-or-ban law threatens to shut off American access to TikTok.

The app, commonly referred to as China's version of Instagram, has been flooded with posts from Chinese users greeting the influx of US newcomers.

One post titled "American please help me" went viral on Monday and received over 10,000 comments after its poster, from Zhejiang, requested help with their English homework.

Other popular posts also featured users, who listed their location as being in the US, offering their assistance for Chinese users' homework.

"Ask me any questions! I can help with your English homework, or answer questions about America (Texas). Thank you for welcoming us TikTok refugees," one post read. Several commenters uploaded photos of English-language worksheets in response.

The surge in American users on Chinese apps has also led to a rise in the hashtag #TikTokRefugee on Xiaohongshu, with dozens of Chinese creators posting guides on how to use the platform. The hashtag itself has been viewed over 64 million times, according to data seen by Business Insider.

"If you see a video that's downright awesome, just comment 6 or 66 or 666," said a cowboy hat-toting user, Big Tooth Chinese Redneck, in one viral video, referencing a Chinese internet slang term.

The sudden interest in Chinese social media platforms comes as TikTok continues to challenge the divest-or-ban law that the Senate passed in April. According to the law, TikTok will have to stop operating in the US on January 19 if its Chinese-based owner, Bytedance, doesn't sell the app.

The divest-and-ban law was passed amid widespread security concerns that the Chinese government could access user data if Bytedance continued to own the platform. TikTok CEO Shou Zi Chew told The Wall Street Journal in 2023 that such concerns are unfounded since the company would work with Oracle to store user data in the US.

TikTok argued its case with the Supreme Court on Friday, saying it will "go dark" in January if the court doesn't extend its divestment deadline. The court is expected to rule on the company's fate this week.

There's a lot on the line for TikTok now — it lost a challenge to the law in December when it brought the case before a panel of three judges from the US Court of Appeals for the District of Columbia Circuit.

In December, President-elect Donald Trump asked the Supreme Court to pause the law until after his inauguration. Trump is set to take office on January 20.

Allowing TikTok to operate in the US is a reversal of Trump's policy position on the company. Trump pushed for a TikTok ban in 2020 when he was still president. But more recently, the president-elect told reporters in December that he had a "warm spot" in his heart for TikTok.

Still, TikTok's troubles have brought unexpected benefits to platforms like Xiaohongshu and Lemon8, which both surged to the top two spots on Apple app store rankings. Lemon8 is also owned by Bytedance.

Meagan Loyst, founder of the investor collective Gen Z VCs, told Business Insider on Monday that users were flocking to these platforms to protest the government's planned TikTok ban.

"It really is just retaliation towards the government in the simplest way, but in a way that feels very native to Gen Z," Loyst said.

Representatives for TikTok and Xiaohongshu did not immediately respond to a request for comment from Business Insider.

• Americans are rushing to download two Chinese social apps, days before a possible TikTok ban.
• Xiaohongshu and Lemon8 rose to the top spots on the Apple app store rankings on Monday.
• Both platforms could be subject to the same divest-or-ban law that's imperiling TikTok.

TikTok users are lamenting that the app could "go dark" in less than a week in the US due to a divest-or-ban law. At the same time, two other apps with Chinese owners have risen to the top of the Apple app store in the US.

On Monday, Xiaohongshu, also known as RedNote, and Lemon8, an app with the same owner as TikTok, hit the top two spots on the Apple app store rankings.

Xiaohongshu functions similarly to Instagram, but with more commerce features, while Lemon8 has been described by creators as a Pinterest-like platform.

The rush to download these apps is a bit of a head-scratcher, as they could be subject to the same divestment requirements as TikTok if the US government chooses to target them. The Protecting Americans from Foreign Adversary Controlled Applications Act applies to social platforms owned by countries that the US government views as foreign adversaries. TikTok became a political target because its owner, ByteDance, is based in China, which the US government has labeled a foreign adversary and Congress views as a national-security risk.

TikTok is clearly subject to the divest-or-ban law, as it's named in the bill's text. But ByteDance is also named, which raises the question of why its other app, Lemon8, is suddenly surging in popularity.

Christopher Krepich, the communications director for the House Committee on Energy and Commerce, previously told Forbes the bill would ban Lemon8 unless ByteDance divested. A spokesperson for the committee did not immediately respond to Business Insider on whether it would apply to Xiaohongshu.

The law was written broadly and could be enforced on any company owned by a foreign adversary that permits a user to "create an account or profile to generate, share, and view text, images, videos, real-time communications, or similar content." That could include Xiaohongshu if the US government chose to target the app.

The law does have some exceptions, including apps where users "post product reviews, business reviews, or travel information and reviews." That suggests Chinese e-commerce platforms Shein and Temu would not be targeted.

ByteDance, Xiaohongshu, Apple, and Google did not respond to requests for comment.

Why users are flocking to these two apps

It's tough to say exactly what's driving mass interest in Xiaohongshu and Lemon8. Some users may be flocking to the apps to find a replacement for TikTok, while others may simply like their product features. In December, Xiaohongshu had around 300 million monthly active users globally, Bloomberg reported.

Another possibility for the downloads surge is that TikTok users are choosing the Chinese apps as a tongue-in-cheek protest of the divest-or-ban law.

"It really is just retaliation towards the government in the simplest way, but in a way that feels very native to Gen Z," said Meagan Loyst, founder of the investor collective Gen Z VCs.

If millennials pioneered "slacktivism" with online petitions, Gen Z seems to be trying something new. You might call it "trolltivism."

"This is not the first time that trolling on a large scale has happened," Loyst said, citing the 2020 incident when TikTok users purchased tickets to Trump rallies. "It's trolling the US government."
