"Girls, there's strength in numbers, let's fly to Beijing and rescue him," one of them posted on microblogging platform Weibo.
Others said they were prepared with shovels to dig tunnels and pliers to cut wired fences.
But it was not long before such discussions - as well as the accounts that shared them - were deleted.
As China's increasingly obsessive celebrity fans continue to make headlines for all the wrong reasons, authorities have made it clear that such behaviour would not be tolerated.
"The chaos in celebrity fan clubs, exposed by the 'Kris Wu incident', shows that bad fan culture has reached a critical moment that must be corrected," the country's top disciplinary body said in a post, adding that thousands of "toxic" fan comments and groups have since been deleted.
Three weeks ago, China's internet watchdog said in a 10-point plan that it would stop the dissemination of "Harmful" information in celebrity fan groups, including gossip and verbal abuse.
Any platforms that do not work to quickly remove such content would also be penalised.
"There needs to be a limitation of irrational star-chasing," it said.
For months, Beijing has ramped up efforts to rein in what it calls "Chaotic" fan culture - a move welcomed even among some celebrity fans.
A Weibo user who regularly posts updates about entertainment news, said: "Crazy fans have really given us all a bad name. Even I get annoyed when I see large groups of fans crowding the airport to see their idols."
Many members of these groups are not just people harmlessly cheering on their favourite stars.
In many instances, their behaviour has turned toxic.
From stalking to cyberbullying and spreading rumours, organised fan groups have increasingly taken their "love" to crazy extremes.
Chinese fans = data labourers
Even though obsessive fan culture is hardly unique to China, experts say that the scale is greater there thanks to a massive internet population that is also highly-engaged.
"Participating in Chinese fandom culture is no longer simply a hobby, but a form of data labour," said Liaoning University's Dr Bai Meijiadai.
From celebrity ranking lists based on followers and engagement, to singing TV contests allowing the public to cast votes, fans have become active participants in feeding the idol worship machine like never before.
