"As a student of acting, he knew how to master the role he was handed. For years, he had been performing the important part of the indispensable servant to perfection, much to the annoyance of Mao, his master. He was almost entirely self-effacing. He knew how to mend the broken pieces of crockery that Mao shattered from time to time. Zhou’s genius for self-abnegation and the deft and artful way that he had of cleaning up a nasty mess aggravated Mao, the master, and piqued his pride. They were the odd couple, but this was no domestic comedy."
