Updated PowerPoint slide for Beijing opera

After grading your assignments on Beijing opera, I have added another slide to the PowerPoint presentation for that day's class, in order to provide more detail on the history of China in the 20th century. In particular, a number of you confused the Communist Revolution (1949) with the Cultural Revolution (1966-1969). The portions of Farewell, My Concubine that we watched do not address the Cultural Revolution.

Be sure to update your copy of the slides if you have downloaded them.
