Grass, like many other things in China, is seen through a political lens. Historically, the Chinese have viewed grass negatively, with parks kept very clean by removing all tufts of grass, as cleanliness is highly valued in the culture. People have been taught that grass can carry diseases, leading to its removal from public spaces.
Moreover, Communist ideology considers grass to be decadent because it is associated with leisure and class distinctions, as it often symbolizes wealth and leisure activities. The idea of hiring workers to cut grass is seen as a form of exploitation, reinforcing negative perceptions of grass in Chinese society.
