There have been a number of performances over the summer that have taken a much darker turn. Performance artist Zhao Lu is famous because in 1989, just before the Tiananmen Square protest happened, she fired an air gun at one of her works of art. Fast forward to 2019, and she puts on a new show called SKU where she appears in what looks like a sort of great pyramid-shaped prism made of perspex. She's up to her ankles in red liquid made to represent blood. It was a very creepy, strange thing to watch in the city in which this protest taking place.
