three mountains: mountain names. According to the "Jing Ding Jian Kang Zhi", "Its mountains are lush and lush, and the three peaks are juxtaposed, and the north and south are connected, so it is named Sanshan". Sanshan Street is now its former site. When Zhu Yuanzhang built the city in the early Ming Dynasty, three nameless hills in the south of the city were also surrounded in the city. These three mountains just blocked the way from the north to the south gate-Jubaomen. It happened that Miyagi was being built in Swallow Lake in the east of the city, so these three mountains were filled into Swallow Lake. After the three mountains were leveled, a street was built at the base of the mountain and named Sanshan Street. Half down in the sky: it's too far to see clearly.
"Three mountains and a half fall out of the sky" is a poem by Li Bai.
It comes from on climbing in nanjing to the terrace of phoenixes, a seven-character poem written by Li Bai. The original poem is as follows:
phoenixes that played here once, so that the place was named for them, have abandoned it now to this desolate river.
the paths of Wu Palace are crooked with weeds, the garments of Jin are ancient dust.
Three mountains and a half fall out of the sky, like this Island of White Egrets dividing the river.
a cloud has arisen between the Light of Heaven and me, to hide his city from my melancholy heart.
