It is said that more than 300 BC, Alexander the Great left the treasures of the country in Baijiameng on the way to Persia. He believes that this highland city is the safest place. However, what I didn't expect was that Alexander died in India at the age of 32 because of yellow fever, and the general who stayed in Baijiamen to take care of the treasures claimed to be the king in the local area. Since then, Bai Jiameng, a kingdom with a Greek cultural background, has experienced five or six kings for more than 150 years. The library in Baijiamen is said to be no less than the library of Alexandria, with a collection of 200,000 books. As a result, the Egyptian dynasty was very embarrassed about this library, prohibiting the export of special paper. and Bai Jiameng invented the alternative parchment, which was widely used as a substitute for paper in medieval Europe. Baijiameng's fine art is also very good. It is called the carving of the Baijiameng faction and is a particularly prominent work in Greek cultural sculpture. Now, all of these items are housed in the Bergama Museum in Berlin, Germany. Baijiameng had a Zeus altar in the past. It is a particularly prominent work in Greek cultural sculpture. It is the largest and most preserved temple of Zeus. It can be said that it was the artistic treasure of the classical architecture at that time, but in the 19th century. Moved to Berlin by the Germans, leaving only a pile of loess for Turkey.
