Mandarin-speaking singers, film stars and celebrities rarely court controversy when it comes to China given Beijing's long track record of punishing those deemed critical of its rule.
A misspoken word can quickly lead to an artist being frozen out of the world's largest Mandarin-speaking market and a career in ruins.
But the willingness of Namewee and Chen to take on taboo subjects has struck a chord as China grows increasingly assertive on the world stage under President Xi Jinping.
"The lyrics are clever because they sound like a love (gone bad) song, but in every line there is a reference to either the fragile 'feelings' of the Chinese government or riffing on Chinese Communist Party rhetoric," DJ Hatfield, a professor of Musicology at National Taiwan University, told AFP.

Over the last four weeks, Fragile has been a top trending YouTube video in Taiwan, Hong Kong, Singapore and Malaysia as well as making smaller waves among Chinese diaspora fans in places like Australia, Canada and the United States.
Within days of the track's release, Namewee and Chen's Chinese social media accounts were taken down and their music censored while state media accused the pair of insulting the country.
China regularly removes songs deemed to be politically incorrect from domestic music streaming services.
In August, the Chinese culture ministry said it would establish a blacklist of banned songs with "illegal content", such as endangering national security.
Namwee and Chen are both currently based in democratic Taiwan and have brushed off their blacklisting.
"When you say I am banned, I don't feel that way," Namewee said Monday. "I feel it's the people who can't listen to this song that are being banned."
The 38-year-old rapper has repeatedly been at the centre of controversy in Muslim-majority Malaysia.
In 2016, he was detained for several days for allegedly insulting Islam over a video partly filmed inside a mosque.
He was arrested again two years later for allegedly insulting Islam with a Lunar New Year video that featured dancers wearing dog masks and performing suggestive moves.
Chen, 27, grew up in Australia but moved to Taiwan in 2009 to pursue a pop career.
After her Chinese social media accounts were pulled, she responded by singing altered lyrics from Fragile's chorus celebrating that she still had access to Facebook and Instagram, which -- like YouTube -- are banned in China.
