Peng resented Mao's personal lifestyle, which Peng considered decadent and luxurious. By the late 1950s, Mao had developed a lifestyle that was out of touch with Peng's preference for modesty and simplicity. Mao enjoyed a private pool in Zhongnanhai and had many villas around China built for him, which he would travel to on a private train. Mao enjoyed the companionship of an ever-changing succession of enthusiastic young women, whom he met either at weekly dances in Zhongnanhai or on his journeys by train. Mao had a costly office suite built for him in Beijing, including a private, book-lined study. When Peng's wife suggested for the couple to spend more free time visiting Mao's quarters, Peng was reluctant and stated that Mao's surroundings were "too luxuriously furnished" for him to tolerate. Throughout the 1950s, Peng continued to refer to the Chairman as "Old Mao," an egalitarian title that was used among senior CPC leaders in the 1930s and 1940s.
