of the day either swimming in the pool or reading political and historical books and reports from government officials by the pool's side. Therefore, a reception room, a bedroom and a study with Mao's favorite books were built, thus creating the Poolside House which allowed Mao to be permanently close to the swimming pool. Eventually, among Zhongnanhai staff, the phrase "you are wanted at the swimming pool" meant that they were ordered to immediately report to Mao. Mao permanently left the Chrysanthemum Library and moved into the Poolside House in 1966, at the beginning of the Cultural Revolution. Especially in his later years, the Poolside House would be the place for visiting foreign leaders to see Mao. This was the case for Richard Nixon and Kakuei Tanaka.
