This article originally appeared on ABACUS Live streamers in China now have a dress code. Although the dress code is quite vague (as any parent knows, “revealing” can be a flexible concept), this is the first time that China's multi-billion dollar live streaming industry is facing more systematic regulations. And as the country tightens the screws on popular entertainment, there are likely more rules to come. Here are some of the things live streamers in China have to avoid. 1) No naughty clothes No revealing, transparent or tight clothes, nothing flesh-colored, no sexy underwear -- and definitely no sexy uniforms. Live streamers have to be careful about how they pick their wardrobe, according to new standards adopted by two Chinese administrative units (so far). But this rule only concerns women, of course – men are still free to dress up as hot nurses . The new rules also stipulate that broadcasters should not wear clothes containing text or information prohibited by national laws and regulations. What does that mean? Well, we're guessing t-shirts with “Free Tibet” are a no-go. 2) No whispering Some people like to get their kicks aurally instead of visually. Autonomous sensory meridian response ( ASMR ) can be described as a feeling of mild euphoria and tingling skin caused by certain sounds – and there’s a whole subset of live streamers dedicated to creating those sounds. Some tap on the microphone or use different objects to bring relaxation to their listeners. And some whisper. For Chinese regulators, this whispering turned out a little too risque. This is why the local antipornography office forced a number of platforms to remove a great bulk of ASMR content even though the content creators claim there is nothing sexual about it. In this case, censors might have taken comments from Chinese internet users describing ASMR as “in-skull orgasm” too literally. This is just one of a number of ways censors have been fighting against pornographic content. Several years ago, China also banned seductively eating bananas .

But it was enough to brandish her as a public enemy. Streaming celebrity Yang Kaili -- known as Lige -- reportedly had 2 million fans, but that following wasn’t enough for her platform of choice Huya, which dumped her like a pile of bricks. This was despite her promise to watch patriotic documentaries and undertake “education on political ideologies”. Yang isn’t the only one. One Kuaishou live-streamer was jailed for 15 days after he “disrespected” the national anthem. And these live streamers are considered lucky -- disrespecting the national anthem in China can get you jailed for 3 years.

In China, controversy about historical events can get just as contentious. Chen Yifer was a streaming darling before someone dug out a 2-year-old video of her making fun of the Japanese invasion of China and mentioning the Nanjing Massacre. This got her banned from streaming platform Douyu (along with plenty of backlash online). Douyu, for its part, said it will uphold “patriotic education” by taking its live streaming hosts on regular visits to history museums and revolutionary landmarks to make sure that they “understand and remember history.” And if you think this only happens in live streaming, China's popular rage comics account got banned after making fun of a communist martyr.

Mothers young as 14 started sharing their lives on Kuaishou. One of the most popular young moms, 19-year-old Yang Qingning, racked up 45 million followers. After receiving criticism from the Chinese government, the platform rushed to apologize, saying that videos by teen moms and teen-moms-to-be could “negatively impact society.” And while many accused Kuaishou of normalizing or even glorifying teenage pregnancy, other online commentators pointed out that poor rural girls rarely have access to information about reproductive health.
