The city is 300 kilometres (190 mi) west-northwest of Shanghai, 1,200 kilometres (750 mi) south-southeast of Beijing, and 1,400 kilometres (870 mi) east-northeast of Chongqing. The downstream Yangtze River flows from Jiujiang, Jiangxi, through Anhui and Jiangsu to East Sea, north to drainage basin of downstream Yangtze is Huai River basin and south to it is Zhe River basin, and they are connected by the Grand Canal east to Nanjing. The area around Nanjing is called Hsiajiang (下江, Downstream River) region, with Jianghuai (江淮) stressing northern part and Jiangzhe (江浙) stressing southern part. The region is also known as Dongnan (東南, South East, the Southeast) and Jiangnan (江南, River South, south of Yangtze).

Zhengtong had the following message delivered to the Great Treasure Prince of Dharma, the Karmapa: <SEP> the tuotuo river (沱沱河, p tuótuó hé, lit. ``tearful river ''is the official headstream of the yangtze, and flows 358 km (222 mi) from the glaciers of the gelaindong massif in the tanggula mountains of southwestern qinghai to the confluence with the dangqu river to form the tongtian river.) in mongolian, this section of the river known as the ulaan mörön or the`` red river''. <SEP> Norbu writes that the Yongle Emperor, following the tradition of Mongol emperors and their reverence for the Sakya lamas, showed an enormous amount of deference towards Deshin Shekpa. The Yongle Emperor came out of the palace in Nanjing to greet the Karmapa and did not require him to kowtow like a tributary vassal. According to Karma Thinley, the emperor gave the Karmapa the place of honor at his left, and on a higher throne than his own. Rossabi and others describe a similar arrangement made by Kublai Khan and the Sakya Phagpa lama, writing that Kublai would "sit on a lower platform than the Tibetan cleric" when receiving religious instructions from him. During his travels beginning in 1403, Deshin Shekpa was induced by further exhortations by the Ming court to visit Nanjing by April 10, 1407. <SEP> nanjing is the transportation hub in eastern china and the downstream yangtze river area. different means of transportation constitute a three-dimensional transport system that includes land, water and air. as in most other chinese cities, public transportation is the dominant mode of travel of the majority of the citizens. as of october 2014, nanjing had five bridges and two tunnels over the yangtze river, which are tying districts north of the river with the city centre on the south bank.
