At the beginning of 2020, a sudden global public health event (new crown epidemic) caught everyone by surprise. PSD (power station of DESIGN), the Design Center of Shanghai Museum of Contemporary Art, initiated the "psD Epidemic Prevention Plan" project, which was officially displayed in the PSA venues and opened to the public for free. This project invited me to create a poster with the theme of "Prevention of Epidemic". With the help of intuitive and powerful visual power, the light of hope is lit up in the cliffs.
