"Invisible" theme poster created for The 13th International Poster Triennial In toyama 2021. The intangible theme poster design is based on the oriental artistic conception, the intangibility of water and air, and is designed with reference to the cloud and water patterns of the Forbidden City in Beijing.

In today's multicultural society, the earth is a village, and we look forward to more integration and tolerance, like water and air, to be invisible.
