Thank you for the introduction of Houston, USA. Great God helps.

Houston is the largest city in Texas, the fourth largest city in the United States and the largest economic center along the Gulf Coast. Covering an area of 1,44 square kilometers, the city was named after Texas and President Sam Houston. Houston is the county seat of harris county (the third largest county in China). Houston is in the east of Missouri, with a part in the southwest extending into Fubian County and a part in the northeast extending into montgomery county. Founded in 1836 and merged in 1837, Houston is one of the fastest growing big cities in the United States and the largest big city without planning law in the United States. In 19, Houston had a population of 45,, ranking 85th in the United States. According to the American census in 2, the total urban population reached 1.9 million (it exceeded 2 million in 24). The greater Houston metropolitan area is the seventh largest metropolitan area in the United States (5,18,443 people in 1 counties). Houston is famous for its energy (especially oil), aviation industry and canals. Houston Port is the sixth largest port in the world and the busiest port in the United States, with the largest tonnage of foreign ships and the second regardless of nationality. The headquarters of Fortune 5 is second only to new york. Houston is home to Texas Medical Center, the largest and most important research and treatment institution in the world. Houston also has the lowest living expenses and housing prices among 27 major metropolitan areas with a population of over 1.7 million in the United States. Houston is called a "global city" by the Research Group and Network on Globalization and World Cities (GaWC). The official nickname of Houston is "Space City" because it is the seat of Johnson Aviation Center and the mission monitoring center is also located here (therefore, "Houston" is the first word said on the moon). Many locals like to call it "Niunuma City". Other nicknames are "H Town", "Paw City" or "Mongolia City". Houston is a multi-cultural city, where many immigrant communities develop. Its art gallery area is a paradise for many cultural institutions and exhibitions, attracting 7 million tourists every year, and active visual performing arts can often be seen in Houston. Houston is most famous for its oil industry, NASA and the Port Of Houston. Houston is an important energy industry town in the world (especially oil). In addition, biochemical industry, aerospace industry and canals are also the industrial bases of most of the city. The Houston metropolitan area contains the world's largest petrochemical industrial area, including refining plastic raw materials, pesticides and soil fertilizers. The region is also the world's leading oilfield equipment manufacturing center. The successful Much of As a Petrochemical Complex is dueto artificial canal in Houston, which is one of the busiest ports in the United States and the second largest tonnage tonnage in the world. Because of these economic and trade, many residents from other parts of the United States have also moved to Houston, and some have come from hundreds of countries around the world. Unlike most regions, high oil prices seem to do harm to the economy, but for Houston, whose main industry is energy industry, high oil prices seem to be beneficial. Historically, there have been several sudden growth peaks (some serious economic recessions) in Houston related to the oil industry. The discovery of oil near Houston in 191 led the first economic take-off here; The population of the city increased to 14, in the 192s. The rapid development of the aerospace industry in this city drove the second growth peak, which was more fixed because of the oil crisis in 1973. Due to the increasing demand for oil in Texas, many people moved to Houston from the northeast to profit from trade. When the embargo was lifted, growth in most other regions almost stagnated. But Pasadena (California) still has its own refinery, and Houston Port is the busiest port in the world. Houston's headquarters is second only to new york in the Fortune 5. The city tried to create its banking system, but the local company numbers in Houston began to be merged by other companies in the country. Banks are still an important system here, but most banks operating here are not based on this. Real estate is also a huge performance in the Houston area. Houston is also the county seat of Harris County. The southwest of Houston is surrounded by Fort Bend County on three sides, and a small part of the northeast corner of Houston extends to Montgomery County. The current mayor of Houston is Bill White, who is currently in his second term. The mayor of Houston can be re-elected for a maximum of two terms of two years, with a total term of three or six years. Among the 14 city councillors, nine are regional councillors elected by their constituencies, and five are at-large councillors elected by the whole city. City councillors are also subject to the same term limit as the mayor. The municipal government is scheduled to increase two constituencies and two regional councillors when the population of Houston exceeds 2.1 million in 21. Houston's excessively strict term limit forced many city councilors to run for other government posts at the end of their terms in order to extend their political lives. Former government officials who meet this situation include Anthony Hall, Rodney Ellis, Sheila Jackson-Lee, Sylvia Garcia, Martha Wong, Chris Bell, and Annis. Lee P. Brown, the former mayor, strongly opposes the existing term limit on the grounds that it prevents current officials from gaining enough municipal experience. The city Council has been discussing whether to modify or cancel the term limit. Some state legislators elected in the greater Houston area also publicly expressed their opposition to the current term limit in Houston.
