How to interpret "short-lived capital"-Nanjing

The peaks of Zhongshan are in the northeast of Nanjing, rolling hills are in the southwest, and Zijin Mountain is in the east. The Yangtze River flows from southwest to northeast. Zhou Mantu's "Jinling Lock" says: "Zheng Danquan said that the Jinling form' the mountains are scattered but not gathered, and the river flows away without staying. Those who are neither emperors nor prime ministers of Zhuang Yuan were deprived of Feng Shui by Shilu because of too many officials. Yu Bao is happy with his theory. " As can be seen from the picture, firstly, the whole Jinling City sits north to south, and Zhonghua Gate is the south gate of Nanjing City. Although there are peaks of Zhongshan Mountain in the north, the dragon "disperses when the wind blows, and the water at the boundary stops". Because it is separated from the dragon's prosperity by the Yangtze River in the northeast, Jinling has lost its long-term support and is in a stormy situation. When building its capital, it will be like sitting east to west, although it can make a fortune by using the water of the Yangtze River. Second, although it was good to choose the big pattern of the back water facing the sun as the urban layout at that time, the water rolling along the Yangtze River flowed from the "back" to the east, without encircling or winding, and it was ruthless. This pattern of wealth destruction is also taboo in Feng Shui theory. Without the involvement of Huaihe River and the nourishment of Xuanwu Lake and Mochou Lake, Jinling Nanjing will inevitably be a "poor city". Third, the water of the Yangtze River flows to the northeast, and the water outlet is in the northeast. As Feng Shui masters know, two of the three major water hazards are in the northeast, so Feng Shui masters believe that the city committed the ugly water, and after 4 years of prosperity, it injured people, especially young people, and 3, people died in the Nanjing Massacre. Just made a footnote for this. 4. The first capital in Nanjing was Dongwu during the Three Kingdoms period. In those days, Zhuge Liang once praised that "the dragon plate in Zhongshan, the stone tiger distance, is really the residence of the emperor!" According to this statement, the Eastern Jin Dynasty, the Song Dynasty, Qi Dynasty, Liang Dynasty and Chen Ye in the Southern Dynasties successively established their capitals in Nanjing, so Nanjing was called the "ancient capital of the Six Dynasties". After the Six Dynasties, Li Yu, Li Houzhu of the Southern Tang Dynasty, also established his capital here. Although the king of national subjugation did not support in Nanjing for a long time, he left many poems, saying, "How much sorrow can you have, just like a river flowing eastward." This is the true portrayal of the king who perished. However, in the seven dynasties, Song, Qi, Liang, Chen and South Tang Dou were in the period of national division, and their founding time was very short. Until the late 14th century, Zhu Yuanzhang of the Ming Dynasty established the capital here and built the Ming Palace in Nanjing, which had a short period of prosperity. However, at that time, there was a fierce debate in the imperial court about whether to continue to regard Nanjing as the capital. In the end, Ming Chengzu accepted the advice of Feng Shui master and moved to Beijing in 1421, which led to the rise and fall of the Ming Dynasty for 223 years. The Taiping Heavenly Kingdom, the first large-scale peasant movement in China's modern history, also established its capital in Nanjing in 1853. As we all know, the Taiping Heavenly Kingdom was also very short. In 1911, the Revolution of 1911 was successful, and Sun Yat-sen became the temporary president in Nanjing, where the Republic of China established its capital. By 1925, Sun Yat-sen died. Although he could rest in the Sun Yat-sen Mausoleum in Nanjing, he could only look at the temporary presidential palace and sigh. From the quotation, it can be seen that although Nanjing has been regarded as the capital city several times, it is short-lived, so Nanjing is known as the "short-lived capital city" in the Feng Shui world. When we comment on Nanjing in this way, we do not deny the prosperity and prosperity of Nanjing as a provincial capital metropolis, but discuss the reasons and historical roots why Feng Shui masters regard Nanjing as a "short-lived capital".
