Chen told the Beijing Music Radio that the order to switch girls were from the highest level, a communism politburo member, 3 days before the opening night, after the last formal rehearsal. Comparing this with news report at the time, the 'politburo member' is Mr. Xi Jinping. Son of Mr. Xi Zhongxun, an senior communism official. Mr. Xi Jinping has been set to replace Mr. Hu Jintao to be the next 'core' of the CCP leadership.
It'll be interesting to see on which scale this unnecessarily stupid act may cost Xi's potential to be the next 'core' of China.
