This system is followed and the Chinese emperor Qin Shi Huang. Fearing that while sleeping he would be killed the conspirators, he used to change room every night, which was asleep. No one could know in advance what kind of room to elect the emperor on the following night. Whenever he team cheerful concubines accompanied by eunuchs transferred their master bed from one end to another palace. Qin Shi Huang did not fear that he will have to sleep twice in the same room. In his palace the number of rooms was so great that, even if he had spent in each of them only one night, it would take as many as 36 years to visit them all.
