In recent years China has witnessed lots of phenomenal constructions. The world's longest high-speed rail line (2.298-kilometer-long), which spans over half of China, began operating at the end of last year. In April, 2012 the world's highest and longest tunnel-to-tunnel bridge was commissioned in China, which linked together two tunnels 1176 meters apart, and 355 meters above Hunan's Dehang Canyon. Again in 2012 Chinese mass media reports, that Changsha, China's Hunan province will be home to world's tallest building, which will be built in just 7 months. 220-store building will be 838 meters high. Today China put into operation world's largest building - New Century Global Center . The superlatives in China continue -- the latest symbol of China's "bigger is much, much better" ethos is open for business. Located in Chengdu (population 14 million), capital of Sichuan province in southwestern China, the New Century Global Center is the "largest freestanding building in the world," Chinese officials say. Though the words "world's largest" usually bring to mind an image of a towering skyscraper, this project actually isn't all that tall. But it's certainly big. At 500 meters long, 400 meters wide and 100 meters high, the 1.7-million-square-meter mega-structure is capable of housing 20 Sydney Opera Houses and almost three times the size of the Pentagon in Washington, D.C. The Global Center, which opened June 28, is home to business offices, hotels, movie theaters, shopping malls, a faux Mediterranean village and family-themed attractions such as a water park called Paradise Island.

Chengdu's New Century Global Centre is latest symbol of China's economic might and massive ambition. New Century Global Centre, located in Chengdu (population 14 million), capital of Sichuan province in southwestern China, is nearly completed. At 500 meters long, 400 meters wide and 100 meters high, Chinese officials are calling the 1.7 million square meter mega structure the largest freestanding building in the world, capable of housing 20 Sydney Opera houses and almost three times the size of the Pentagon in Washington. The Global Centre will house offices, conference rooms, a university complex, two commercial centers, two five star hotels, an IMAX cinema, a "Mediterranean village", a skating rink and a pirate ship, among other attractions. About 400 thousand square meters will be devoted to shopping, most of the outlets high-end luxury brands. Despite Chengdu being around a thousand kilometers from the sea the complex has a marine theme, with fountains, a huge water park and an artificial beach, accented by the undulating roof, meant to resemble a wave. This is an ocean city built by man. There will be 1000 rooms (in the hotel) and all will have seaside views. The thick smog that normally blankets Chengdu risks making it a sunless sea, but visitors will not need to worry about that, as designers borrowed a Japanese technique. There will be an artificial sun that will shine 24 hours a day and allow for a comfortable temperature. The system uses specialized lighting technology that heats as well as illuminates. A giant screen 150 meters long and 40 meters high will form the horizon and offer sunrises and sunsets, accompanied by nautical breezes. The centerpiece will be a 5 thousand square meters artificial beach, to include a rafting course and a "seafront" promenade, complete with parasols and seafood outlets that can accommodate 6 thousand people. Ground was broken for the New Century Global Centre in 2010 and (the building) is estimated to open to the public this April. In recent years China has witnessed lots of phenomenal constructions.
