Example Input: Article: Chinese New Year Celebration is the most important celebration of the year. Chinese people may celebrate the Chinese New Year in slightly different ways but their wishes are almost the same; they want their family members and friends to be healthy and lucky during next year. Chinese New Year Celebration usually lasts for 15 days. Celebratory activities include Chinese New Feast, firecrackers, giving lucky money to children, the New Year bell ringing and Chinese New Year Greetings. Most of Chinese people will stop the celebrating in their home on the 7th day of New Year because the national holiday usually ends around that day, however celebrations in public areas can last until the 15th day of New Year. It is the money given to kids from their parents and grandparents as New Year gift. The money is believed to bring good luck, ward off monsters; hence the name "lucky money". Parents and grandparents first put money in small, especially-made red envelopes and give the red envelopes to their kids after the New Year's Feast or when they come to visit them on the New Year. They choose to put the money in red envelopes because Chinese people think red is a lucky color. They want to give their children both lucky money and lucky color.

Example Input: Article: In August 2015, President Obama announced that North America's highest mountain, Mount McKinley, would be renamed. Its new moniker , Denali, was actually its original Aleut name, meaning "the high one". The previous name, on the other hand, only dates back to 1896--the year when it was named in honour of William McKinley(1843--1901), who was shortly to become President of the United States. Denali is of course not the only mountain with an interesting linguistic history, so let's travel to Asia, and across Europe, to explore the naming of those continents' most famous peaks and mountain ranges. The Nepalese name Himalaya comes from a Sanskrit word meaning "Abode of Snow", from hima for "snow" and alaya for "abode". In Buddhist sources, Himalaya is known by various names such as Himava and Himavanta. In 1856, Mount Everest was named after Sir George Everest (1790--1866), who was the superintendent of the Trigonometrical Survey of India. Everest himself was initially displeased by the naming, since he feared that local inhabitants might not be able to pronounce it. K2 stands for Karakoram 2, because it was the second peak to be surveyed in the Trigonometrical Survey in the Karakoram system. It was also formerly known as Mount Godwin Austen after Col. H. H. Godwin Austen, who first surveyed it. Another alternative name for the mountain is Chhogori. Annapurna is a household Goddess for Hindus, who guarantees to her worshippers that food will not fail. The name derives from a Sanskrit word meaning "one who gives nourishment". The Matterhorn's name derives from the name of the nearby town of Zermatt, the second element of which is apparently Matte "meadow", and Horn, "horn". Horn is not an unusual element in German names of mountains with jutting peaks. The mountain is called Mont Cervin in French and Monte Cervino in Italian, from the Italian adjective cervino "deer-like", which conjures up a deer's antlers. Ben Nevis is the Anglicized form of the Scottish Gaelic name Beinn Nibheis, which means"Mountain by the(River)Nevis". The name of the river apparently derives from a Celtic root for "water".
