Supermarkets, shopping malls, and farmers' markets are the most concentrated places where plastic bags are used, and currently most of them provide plastic bags for free. In order to guide people to use plastic bags reasonably and save them, starting from June 1, 2008, a paid-use system for plastic bags will be implemented in all supermarkets, shopping malls, and farmers' markets, and plastic bags will not be provided for free. Retail establishments must clearly mark the price of plastic bags and charge customers separately for the cost of the plastic bags; they may not provide them free of charge or include the cost of the plastic bags in the total price of goods.
