Morality and history. Jiangxi is called "Gan" for short. It was named as a province because Tang Xuanzong set up a west road in the south of the Yangtze River in 733 A.D., and the largest river in Jiangxi is Ganjiang, which is one of the inland provinces in China. Morality and history are open-book exams. The first grade (grade seven), that is, the first grade of junior high school, is the primary stage of middle school career and an important stage of adapting from primary school to middle school.
