Slaves to humor

The fracas around a comedy star and his former apprentice has put a spotlight on China's outdated apprenticeship system, which is not the best way to train budding talent.

In 2010, Guo Degang and Cao Yunjin had a fallout. It took them six years to hang out the dirty laundry in public.

Both Guo and Cao are famous comedians specializing in the genre of cross-talk, or xiangsheng, which is the Chinese equivalent of standup comedy in the United States.
