A month after the 29th anniversary of the Tiananmen Square massacre in China, a Shanghai woman has engaged in a surprising act of defiance against her government.

Dong Yaoqiong dumped ink on a billboard photo of Chinese president Xi Jinping.

Then she posted video of this protest on social media using the @feefeefly Twitter account.

"I am in the Lujiazui district of Shanghai right now, and that's the Haihang building just behind me," Dong says in the video. "It's pretty early, and I think everyone is still on their way to work."

Then she points toward the photo of the president.

"What I want to say is that I am using my real name to oppose Xi Jinping's tyranny and dictatorship—and the oppressive brain control perpetrated on me by the Chinese Communist Party," she said, according to Radio Free Asia.

Then, according to the Hong Kong Free Press site, she went home and posted photos of police officers that she took through the peephole in the door.

The woman hasn't been seen since and her Twitter account has been deactivated, which has raised concerns among Hong Kong human-rights activists.

Trade war looms between U.S. and China

Meanwhile, the trade war between America and China is about to begin.

That's because on Friday (July 6), a new 25 percent import tax on $50 billion worth of Chinese goods goes into effect.

The government headed by Xi is expected to retaliate.

U.S. president Donald Trump has said that if this occurs, he will expand trade measures to ensure that $100 billion worth of Chinese imports face this tax.
