What is the main content of Chongzhen almanac?

In the almanac of Chongzhen, missionaries adopted the cosmological system of tycho brahe (1546 ~ 160 1), introduced Ptolemy's current even wheel system, and quoted Copernicus, Galileo and Kepler (1571~). However, due to the prejudice of Jesuit priests against Copernicus' theory, they did not talk about Copernicus' cosmic system. In addition, before Kepler announced the planets of the three laws of motion of the solar system 1609 to 16 19 years ago, some of them had already left Europe and came to China, while others left Europe and came to China at this time or later, so the Calendar of Chongzhen did not introduce Kepler's great discoveries, but only translated some of Kepler's books on the movement of Mars.
