@@jameslinmd Jin dynasty was a political power created by what was called the "Manchus", a nomadic northern people who were the direct ancestors of the last dynasty of China, the Qing dynasty. They conquered the Liu Dynasty, and then destroyed the Northern Song dynasty in 1127. The Jin dynasty occupied the vast land which is now northern China and was the first dynasty which set up its capity of what is presently known as Beijing. They were in turn conquered by the Mongolian and absorted into the Yun dynasty, which was itself replaced by the Ming dynasty in 1368. In 1644 the Jin dunasty made a come back and replaced the Ming dynasty until 1911. Words have it that when replacing the Ming dynasty, in order to reduce the hatred of the Hon people due to the Jin's brutiality in 1127 in destroying the Northern Song dynasty, the Jin people changed the name of their dynasty to Qing, which are similar in pronounciation but totally different in meaning and writing. There are many lesser known dynasties in Chinese history. Some are short lived, and some formed by minority nomadic peoples which were not treated as "orthodox" in traditional Chinese history. But modern China recognizes the status of minority peoples and treat them as part of the Chinese peoples, those "unorthdox" dynasties are getting recognized as part of the Chiense dynasties.
