Question: Where does the Great Wall end, in the country where the majority of steel comes from?

full_context: Document 1: Steel industry in China: In 2011 China was the largest producer of steel in the world producing 45% of the world's steel, 683 million tons, an increase of 9% from 2010. 6 of 10 of largest steel producers in the world are in China. Profits are low despite continued high demand due to high debt and overproduction of high end products produced with the equipment financed by the high debt. The central government is aware of this problem but there is no easy way to resolve it as local governments strongly support local steel production. Meanwhile, each firm aggressively increases production. Iron ore production kept pace with steel production in the early 1990s but was soon outpaced by imported iron ore and other metals in the early 2000s. Steel production, an estimated 140 million tons in 2000 increased to 419 million tons in 2006. Much of the country's steel output comes from a large number of small - scale producing centers, one of the largest being Anshan in Liaoning.
Document 2: List of countries by oil production: The top three producers have in recent history been (alphabetically) Russia, Saudi Arabia, and the United States. Each of these countries experienced major production declines at different times in the past, but since 2014 all three have been producing near their peak rates of 9 to 11 million barrels per day. Saudi Arabia and Russia also top the list of oil exporting countries, while Russia is not a member of OPEC. The monthly U.S. oil production reached 10.07 million b / d in November 2017, the highest monthly level of crude oil production in U.S. history. In early 2018, the U.S. government forecast the country will become a net oil and gas exporter by 2022, the first time since 1953.
Document 3: Great Wall of China: The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east - to - west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger and stronger, are collectively referred to as the Great Wall. Especially famous is the wall built in 220 -- 206 BC by Qin Shi Huang, the first Emperor of China. Little of that wall remains. The Great Wall has been rebuilt, maintained, and enhanced over various dynasties; the majority of the existing wall is from the Ming Dynasty (1368 -- 1644).

Document 6: Mausoleum of the First Qin Emperor: The Mausoleum of the First Qin Emperor (Qin Shi Huang) () is located in Lintong District, Xi'an, Shaanxi province of China. This mausoleum was constructed over 38 years, from 246 to 208 BC, and is situated underneath a 76-meter-tall tomb mound shaped like a truncated pyramid. The layout of the mausoleum is modeled on the Qin capital Xianyang, divided into inner and outer cities. The circumference of the inner city is 2.5 km (1.55 miles) and the outer is 6.3 km (3.9 miles). The tomb is located in the southwest of the inner city and faces east. The main tomb chamber housing the coffin and burial artifacts is the core of the architectural complex of the mausoleum.
Document 7: Ship breaking: In 2012, roughly 1,250 ocean ships were broken down, and their average age was 26 years. In 2013, the world total of demolished ships amounted to 29,052,000 tonnes, 92% of which were demolished in Asia. India, Bangladesh, China and Pakistan have the highest market share and are global centres of ship breaking, with Chittagong Ship Breaking Yard in Bangladesh, Alang in India and Gadani in Pakistan being the largest ships' graveyards in the world. The largest sources of ships are states of China, Greece and Germany respectively, although there is a greater variation in the source of carriers versus their disposal. The ship breaking yards of India, Bangladesh, China and Pakistan employ 100,000 workers as well as providing a large amount of indirect jobs. In Bangladesh, the recycled steel covers 20% of the country's needs and in India it is almost 10%.
Document 8: List of countries by gold production: For many years until 2006, South Africa was the world's dominant gold producer, but recently other countries with large surface area have surpassed South Africa: China, Russia, Canada, the United States, Peru and Australia. Albeit, none of these countries have approached South Africa's peak production which occurred in the 1970s. Note the figures are for primary production. In the US, for example, for the years 2010 - 14, new and old scrap exceeded both primary production and reported domestic consumption.
Document 9: Shanhai Pass: Located south of Yan Mountain, and north of the Bohai Sea, for centuries the pass guarded the narrow passage between Northeast and Central East China. Both the Northern Qi Dynasty and the Tang Dynasty constructed passes here. In 1381, Ming general Xu Da constructed the present pass, which was named Shanhaiguan (literally "mountain-sea-pass") because of its position between the mountains and the sea. In the late 16th century, Ming general Qi Jiguang began fortification and construction of a military city around the pass, building cities and forts to the east, south and north, making it one of the most heavily fortified passes in China. Today it is one of the best preserved passes in the Great Wall.
Document 10: Great Wall of China: The Great Wall stretches from Dandong in the east to Lop Lake in the west, along an arc that roughly delineates the southern edge of Inner Mongolia. A comprehensive archaeological survey, using advanced technologies, has concluded that the Ming walls measure 8,850 km (5,500 mi). This is made up of 6,259 km (3,889 mi) sections of actual wall, 359 km (223 mi) of trenches and 2,232 km (1,387 mi) of natural defensive barriers such as hills and rivers. Another archaeological survey found that the entire wall with all of its branches measure out to be 21,196 km (13,171 mi). Today, the Great Wall is generally recognized as one of the most impressive architectural feats in history.
Document 11: List of countries by steel production: In 2017, total world crude steel production was 1,691.2 million tonnes (Mt). The biggest steel producing country is currently China, which accounted for 49.2% of world steel production in 2017. In 2008, 2009, 2015 and 2016 output fell in the majority of steel - producing countries as a result of the global recession. In 2010 and 2017, it started to rise again.
Document 12: Great Wall of China: The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east - to - west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups of the Eurasian Steppe with an eye to expansion. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger and stronger, are collectively referred to as the Great Wall. Especially famous is the wall built in 220 -- 206 BC by Qin Shi Huang, the first Emperor of China. Little of that wall remains.

Document 14: Great Wall of China: One of the most striking sections of the Ming Great Wall is where it climbs extremely steep slopes in Jinshanling. There it runs 11 km (7 mi) long, ranges from 5 to 8 m (16 ft 5 in to 26 ft 3 in) in height, and 6 m (19 ft 8 in) across the bottom, narrowing up to 5 m (16 ft 5 in) across the top. Wangjinglou (t 望京樓, s 望京楼, Wàngjīng Lóu) is one of Jinshanling's 67 watchtowers, 980 m (3,220 ft) above sea level. Southeast of Jinshanling is the Mutianyu Great Wall which winds along lofty, cragged mountains from the southeast to the northwest for 2.25 km (1.40 mi). It is connected with Juyongguan Pass to the west and Gubeikou to the east. This section was one of the first to be renovated following the turmoil of the Cultural Revolution.
