On the morning of July 4th, a young woman live-streamed herself splashing ink on an image of Xi Jinping in front of a Shanghai office building while speaking out against one-party rule in China.

In the video, the woman surnamed Dong shouts out in protest, “I oppose Xi Jinping’s autocratic rule and tyranny!” before then splashing black ink onto Xi’s face in a “Chinese dream” poster located on the street in front of the HNA Building in Pudong.

The young woman also claims to have been under Chinese Communist Party “mind control” for the past year, asking international organizations to intervene and investigate this issue.

Dong then went on to taunt the Chinese president, declaring, “Xi Jinping, I’m waiting here for you to catch me! I splashed ink onto your portrait in front of your property.”

And it seems that is exactly what happened. According to RFI, a reporter successfully contacted Dong through her Twitter account and confirmed that she was safe at around 2 pm yesterday. However, an hour later, Dong posted a photo on Twitter of what appears to be multiple officers standing outside her door.

“Right now, there are people in uniform outside my door. Once I get changed, I will go out. I haven’t done anything wrong. The ones who have done wrong are the people and organizations that hurt me,” she wrote.

Dong has not been heard from since. Her Twitter account @feefeefly has also been taken down.

On Twitter, many netizens have expressed their concern for the young woman’s safety. Some have tracked down her personal details and contact information, but have so far been unable to reach her.

Of course, in China, public criticism of Xi Jinping and one-party rule is not allowed. Those who break this prohibition can face severe consequences. People have put on trial for merely giving China’s leader nicknames like “Steamed Bun Xi.” These restrictions have only become stricter with the removal of presidential term limits earlier this year, allowing Xi to stay in power for life.

It’s not clear what will become of Dong. Back in 2015, a man was sentenced to 14 months behind bars for hurling a bottle of ink at the portrait of Mao Zedong looking out over Tiananmen Square.
