The Baishazhou Yangtze River Bridge (), sometimes referred as the Third Wuhan Yangtze River Bridge for being the third Yangtze river bridge in Wuhan, is a highway bridge over the Yangtze River in Wuhan, Hubei Province, China.
 It is located 6.8 kilometers southwest (upstream) of the First Bridge (which connects central Wuchang with central Hanyang).
 The two bridge names come from the order of construction (it was built after the First and Second Bridges), and from the name of the small island (Baisha Zhou (白沙洲), i.e. "White Sand Island") located under the bridge.
The Yangtze Patrol, also known as the Yangtze River Patrol Force and Yangtze River Patrol or YangPat and ComYangPat, from 1854–1949, was a prolonged naval operation to protect American interests in the Yangtze River's treaty ports. Initially the patrol was carried out by ships of the United States Navy's East India and Asiatic Squadrons.
 In 1922, the "YangPat", an abbreviated shortening of Yangtze Patrol, was established as a formal component and assigned to the Asiatic Fleet.
 Under the unequal treaties, the United States, Japan, and various European powers, especially the United Kingdom, who had been on the Yangtze, since 1897, were allowed to cruise China's rivers.
 They also, patrolled coastal waters, protecting U.S. citizens, their property, and Christian missionaries.
 The Yangtze is China's longest river, and very important for commerce.
 Ocean-going vessels were able to proceed as far upstream as the city of Wuhan.
 This squadron-sized unit cruised the waters of the Yangtze as far inland as Chungking, more than 1300 mi from the sea, and occasionally far beyond.
The Yangtze River Delta or YRD is a triangle-shaped metropolitan region generally comprising Wu-speaking area, Shanghai, southern Jiangsu province and northern Zhejiang province of China.
 The area lies in the heart of the Jiangnan region (literally, "south of the River"), where Yangtze River drains into the East China Sea.
 The urban build-up in the area has given rise to what may be the largest concentration of adjacent metropolitan areas in the world.
 It covers an area of 99,600 km2 and is home to over 115 million people as of 2013, of which an estimated 83 million is urban.
 If based on the greater Yangtze River Delta zone, it has over 140 million people in this region.
 Having a fertile soil, the Yangtze River Delta abundantly produces grain, cotton, hemp and tea.
The term Three Furnaces () refers to the especially hot and oppressively humid summer weather in several major cities in the Yangtze River Valley, within China.
 It was coined during the Republican period of China, and refers to the following cities:
Chongming-Qidong Yangtze River Bridge or the Chongqi Bridge (), also called Chongqi Crossing Project (), is a bridge across the north fork of the Yangtze River, near the river's mouth between Chongming Island of Shanghai and Qidong in Jiangsu Province.
 This bridge, along with the Shanghai Yangtze River Tunnel and Bridge to the south, forms the last crossing of the Yangtze River before the river empties into the East China Sea.
 The bridge carries the six-lane G40 Shanghai–Xi'an Expressway, part of the National Expressway Network of the People's Republic of China.
Jiangxia District () is one of 13 districts of Wuhan, the capital of Hubei province, People's Republic of China, situated on the eastern (right) bank of the Yangtze River.
 Jiangxia district has an area of 2009 km2 and a population of 680,000.
 It is the southernmost and most sparsely populated of Wuhan's districts.
 It borders the districts of Caidian and Hannan across the Yangtze and Hongshan to the north, as well as the prefecture-level cities of Ezhou to the east, Huangshi to the southeast, and Xianning to the south.
Luzhou (; Sichuanese Pinyin: Nuzou; Luzhou dialect: ), formerly transliterated as Lu-chou or Luchow, is a prefecture-level city located in the southeast of Sichuan Province, China.
 The city, named Jiangyang until the Southern and Northern Dynasties, is known as the "wine city".
 Situated at the confluence of the Tuo River and the Yangtze River, Luzhou is not only an important port on the Yangtze river, but also the largest port in both size and output in Sichuan province since Chongqing seceded from Sichuan province in 1997.
Xianning () is a prefecture-level city in southeastern Hubei province, People's Republic of China, bordering Jiangxi to the southeast and Hunan to the southwest.
 It is known as the "City of Osmanthus".
Hannan District () is one of 13 districts of Wuhan, the capital of Hubei province, People's Republic of China.
 It is the least-populous of Wuhan's districts, and is situated on the northern (left) bank of the Yangtze River.
 It borders the districts of Caidian to the north and Jiangxia to the east across the Yangtze, as well as the prefecture-level cities of Xianning and Jingzhou (for a sliver) to the south; it also borders the directly administered county-level city of Xiantao to the west.
The Jiangyin Yangtze River Bridge () is a suspension bridge over the Yangtze River in Jiangsu, China.
 The bridge has a main span of 1385 m connects Jiangyin south of the river to Jingjiang to the north.
 When the bridge was completed in 1999, it was the fourth longest suspension bridge span in the world and the longest in China.
 Several longer bridges have since been completed in China and abroad but it still ranks among the ten longest bridge spans in the world.
 The bridge was also the furthest downstream on the Yangtze until the completion of the Sutong Yangtze River Bridge in 2008 and the Chongming–Qidong Yangtze River Bridge in 2011.
