 For example, in one piece entitled "Ruined City" constructed at the Capital Normal University in 1996, Yin took 1,400 grey roof tiles, rubble, and objects directly from the site of a demolished building in Beijing and she used personal possessions such as a set of four wooden chairs from her marriage with Song Dong; transformed it into an installation piece that commemorated the essence of a city that was lost in the process of modernization.Her work is also notable for its early engagement with environmental concerns.In 1995, as part of a public art event called "Keepers of the Waters" in Chengdu organized by American ecofeminist artist Betsy Damon, Yin created "Washing the River," a performance piece involving ten cubic meters of frozen river water that she invited the public to wash until they melted away.
