Purple Mountain Observatory (PMO) is a modern institute of Chinese Academy of Sciences, whose precursor was The National Institute of Astronomy, Academia Sinica established in 1928. Vicissitudes in the past 80 years reflected the development of modern Chinese institute, and has written the typical course of Chinese Astronomy. Most disciplines of modern Chinese astronomy and observatory stations were branched from here and therefore PMO is known as the cradle of Chinese modern astronomy. Since the founding of New China, PMO got the attention of national leaders. Four generations of Chinese leaders, Mao Zedong, Deng Xiaoping, Jiang Zeming and Hu Jintao, all visited PMO. All achievements in the development of PMO are originated from glorious traditions and depth knowledge and experiences over the generations with their wisdom and hard works. PMO benefited a lot from the great era rejuvenating the nation rely on science and education under the reforms and nation’s opening to the outside world. The developments have been profited greatly from the support from the academy and all due to the joint effort of all people in PMO. The growth of PMO has got substantial supports at all levels, collaborating institutes, universities, various social sectors, international friends, and devoting contribution of friends who worked or studied in PMO. Here, I wish to express my sincere thanks and gratitude to them all.
　 Owing to the enduring work of several generations of scientists, PMO has now become a modern institute with solid foundation and established reputation. There are 4 major research divisions: radio astronomy, space astronomy, astrophysics and celestial mechanics. The observatory operates observing stations over China: Qinghai, Xuyi, Honghe, Yaoan, Ganyu, Qingdao. Qinghai station is for millimeter-wave radio astronomical observation which is equipped with a 13.7m millimeter-wave radio telescope which is operated in a level of international standard. Xuyi station is a unique site for applied celestial mechanics.  PMO is hosting the Key Laboratory of Radio Astronomy, Chinese Academy of Sciences, Center for Space Objects and Debris Observation and Study, Chinese Astronomical Society, and Chinese Astronomical Society. PMO is publishing Acta Astronomica Sinica. Chinese Center for Antarctic Astronomy was initiated by PMO and other institutes in 2006 and is now affiliated with PMO. With authorization of Academic Degree Committee of the State Council, our institute offers a complete spectrum of degree programs such us doctorate and master degrees in ‘Astrophysics’ and ‘Astrometry and Celestial Mechanics’. PMO also provides post-doctorial research program.
　 The world is on the eve of revolution of new science and technological innovation. China is aimed at constructing innovative country and national innovation system. PMO meets a new period of development and will focus on several selected areas, such as dark matter and space high energy exploration, antarctic astronomy, space debris observation and surveillance, planetary sciences and deep space exploration, to make fundamental, prospective and breakthroughs achievements.
　 PMO asks for the continuous supports from the government and society on her development. It will extend close collaborations with both domestic and foreign institutes. We cordially invite you to make your visit to PMO and we invite elites to join PMO. PMO welcomes outstanding students to study in the institute.
