In keeping with the Communist (and Confucian) passion for naming and quantification, Beijing has a museum for everything -- police, bees, even the humble watermelon. If you share this passion and plan on spending a week or more in the capital, invest in a bowuguan tong piao (¥80), which grants you free (or half-price) admission to 98 sites in and around Beijing. You can buy the museum pass at full-service post offices around town.
