Fifth Avenue is the central avenue of Manhattan in New York, USA, lined with gleaming high-rise buildings with glass facades. Men in suits and leather shoes and women in fashion carry briefcases, in and out of high-rise buildings, presenting an elegant and fashionable picture of modern American life. It is synonymous with "highest quality and taste", and its reverence and opulence came from the fact that wealthy New Yorkers in the early 19th century chose their homes at the southernmost end of what was then just a country lane, and today it is the center of New York's business, residence, culture, shopping and tourism.

Few streets offer as many well-stocked, beloved shops as Fifth Avenue. Many of these stores have multiple branches and are world-renowned. You can find almost all the famous shops you can think of on this street, and almost all the products you can think of can be found here. Abundant goods, complete brands, high-end and high-quality have become the characteristics of Fifth Avenue in the United States, and the operation of the brand has become the prominent feature of Fifth Avenue, where every inch of land is valuable. And Elizabeth Arden's Fifth Avenue perfume is produced by the Manhattan skyscraper as the side line of the bottle, and it is said that its faint floral fragrance appropriately expresses the confident, modern, intelligent, intellectual, and elegant side of the female surname, interpreting the elegance, gorgeousness, taste, fashion and vitality of New York's Fifth Avenue, making the perfume maniac have an urge to drink her. For more than 100 years, Fifth Avenue has stood at the pinnacle of success, and there is no reason to doubt that Fifth Avenue will not be able to continue its success for another 100 years.

Fifth Avenue is also a traditional route for New Yorkers to celebrate, and on summer Sundays it is a pedestrian street that is closed to cars. From its humble beginnings as empty farmland in the early 19th century, Fifth Avenue expanded to become one of New York's high-end residential districts, places of celebrity and gentry, and high-end shopping stores. In the 20th century, Fifth Avenue became a place of skyscrapers, with the Empire State Building completed in 1934 as the tallest building.

In addition to these, Fifth Avenue is also a paradise for hip-hop, where there is a need for unknown hip-hop palace-level existence, and they dance freely on Fifth Avenue. They all have free souls, not bound by anything, although they have a strong hip-hop dance strength, but they are unknown. They all have their own arrogance and cannot be subservient, especially the Big Ten of Fifth Avenue, who put an end to the challenge of dance lovers all over the world. The people in these ten positions are not fixed, if they are challenged and fail, they will lose the position of giants, and the ten giants are god-like beings in the Fifth Avenue, and they are worshiped by everyone, and they are the faith of the dancers. In front of the Big Ten Giants, even a figure like Michael Jackson back then needs to perform the gift of a disciple in front of the Big Ten Giants.

In a café near Fifth Avenue, although it is morning, there are many customers here, and they are mainly young people. This café is a style that young people like because the owner is also a young man, and the waiters in the shop are all young and handsome. What's more, the waiters here are not only Westerners, but also of all ethnic groups, so it attracts a lot of young people.

"Hey, Allen, sing us a song." A blonde beauty with a western face said to the waitress who had just brought her coffee.

"Kelly, I've said it many times, I'm working now, and my job is a waitress and not a singer." The waiter with the oriental face, that is, Allen, said a word to the beauty with a smile, and then turned to continue working. Allen, Liu Xiyuan, South Korean, was born on October 24, 1991, and he still has more than a month to turn 19 years old.

"Allen, it's a waste for you not to be a singer like this, you can be the next justinbieber." Kelly persuaded again. Kelly can say that Allen is a big fan, and on Christmas Day in '08, Kelly and her friends went to Fifth Avenue and saw Allen's performance, and they were completely hooked on Allen. Now, for almost two years, whenever Allen appears on Fifth Avenue, Kelly will basically appear, because Allen will basically only perform when he is on Fifth Avenue. Only when he appears on Fifth Avenue will Allen incarnate into the domineering A.L of Fifth Avenue that people can't ignore, and elsewhere, he is just a polite Allen. On Fifth Avenue, after putting on the mask, Allen will be transformed into a domineering A.L., but usually, he is a very quiet Allen. Because Allen has been wearing a mask to perform, there are not many people who know that Allen is A.L., except for Allen's friend, that is, only Kelly and a sister, others will not associate Allen with the domineering A.L at all.

"Kelly, let's not talk about this anymore, okay? And please don't say anything like that, I'm Allen. Allen opened his mouth and said, in fact, Allen, Liu Xiyuan is a Korean, and because of his special experience when he was a child, he was a little autistic. And when I was under the age of 14, I was able to apply to the United States, firstly, to leave South Korea, and secondly, to want to train myself in the United States. I went to Fifth Avenue with a very good friend of mine, and that friend went by force, and after going to Fifth Avenue, Allen would only perform while wearing a mask.

As a situation with no relatives in the United States, Allen really put in a lot of effort to apply to study in the United States alone. The main reason why Allen chose the United States is the high scholarship of the school, and all the tuition fees of Allen have been earned by scholarships over the years. Over the years, Allen has returned to South Korea twice a year, as well as various expenses such as tuition and food, and Allen has also saved tens of thousands of dollars in savings, that is, more than 10 million won. And these are all obtained by Allen through his own efforts, a 19-year-old graduate student, which is relatively rare anywhere, and if you continue to work hard, it is not difficult to study for a doctorate.

Allen has been living in New York for more than five years, and he expects to stay for a few more years, do a Ph.D., get a job, and bring his grandmother and sister to live in the United States, and now Allen is working towards that goal.
