In Hong Kong, wet markets are most frequented by older residents, those with lower incomes, and domestic helpers who serve approximately 10 percent of Hong Kong's residents. Most neighbourhoods contain at least one wet market. Wet markets have become destinations for tourists to "see the real Hong Kong". Many of the wet market buildings are owned by private property investment firms and as a result the price of food can vary from market to market. Hong Kong's wet markets are known to use red lampshades to make the food look fresher.
