Why is Nanjing called "the ancient capital of the Six Dynasties"

Because Nanjing was the capital of Jiangsu Province, Anhui Province and jiangnan province Province.

Nanjing has a long history. The city itself is a treasure trove of geomantic omen, which was coveted by many foreigners in the past. Its beautiful scenery and beautiful environment make its tourism development increase year by year. Many people travel to Nanjing to see the landmark buildings and scenery of this new first-tier city in China, but Suzhou is the strongest prefecture-level city, and its strength is stronger than Nanjing in some aspects. ?

However, Nanjing is the capital of Jiangsu, and its development has certain advantages, and its geographical position is also superior. At the border between Jiangsu and Anhui, frequent exchanges with Anhui have also promoted Anhui's economy to a certain extent, and it has been called the "economic capital" of Anhui by netizens.

In the past, Nanjing was regarded as the capital of Taiwan Province, so many people called it "the capital of three provinces". In China, only Nanjing has such a title, and its popularity and influence are enormous, so it is called "the second city of the Yangtze River Delta" in terms of comprehensive strength.
