The astronomical calendar Qizheng Tuibu, issued in 1477 in China, has played a very important role in the scientific exchanges and cooperation between the Mediaeval Islamic and the Chinese astronomers and has been used for the predictions of the solar and lunar eclipses for more than 270 years. The Ptolemaic model for the motion of the Sun has been introduced in the Qizheng Tuibu with the double eccentricity of 0.0351295, and to the other two imperial calendars of the early period of the Qing Dynasty (1644-1911), Xiyang Xinfa Lishu (1645) with 0.03584 and Yuzhi Lixiang Kaocheng (1724) with 0.0358416. The model for the motion of the Moon in Almagest has been applied in the Qizheng Tuibu with different underlying parameters, and the maximum values for the equation of Center, the equation of Anomaly, Increment, Proportion and the Lunar latitude are different from that of the Ptolemaic tradition, Maragha and Samarkand Observatories.
