Tulsa, located in northeastern Oklahoma, USA, on the banks of the Arkansas River, is the second-largest city in the state and is known as the "Oil Capital of the World" and the "Art Capital of the U.S.A." In the early 1900's, the oil discovery led to a rapid rise to the center of the global energy industry. The city's rapid rise to global prominence in the early 20th century as a result of the oil discoveries has led to the creation of a global energy center, and the city still retains a rich heritage of the oil industry with historic landmarks such as the Kindred Oil Building. Today, Tulsa's economy has diversified to encompass aerospace, technology, and healthcare, and is an important base for companies such as Boeing and Chevron. Culturally, the Brooklyn Arts District brings together more than 20 galleries and studios, the Philbrook Museum and the Tulsa Performing Arts Center highlight its artistic vitality, and the annual Tulsa Arts Week attracts art lovers from around the world. The city's perfect blend of historical heritage and modern innovation makes it an ideal place to experience the unique charm of middle America.
São Tomé and Príncipe is an island country in west-central Africa, consisting of the islands of São Tomé and Príncipe and the surrounding islets, with the capital, São Tomé, located in the northeastern part of São Tomé. Located on the Gulf of Guinea, about 200 kilometers from the African continent, the country was colonized by Portugal in the 15th century and became independent in 1975, with Portuguese as the official language and an economy based on agriculture (cocoa, palm oil) and tourism. It should be noted that "Java" is not a city or region of the country; Java is the main island of Indonesia, with cities such as Jakarta and Surabaya, and has nothing to do with São Tomé and Príncipe, possibly due to a confusion of names.
