In the United States, the sale of valuable works of art is mostly through galleries organized by art dealers, but the authors do not usually stand to sell their works. That's why in America, art galleries are springing up like mushrooms. People are divided into many types of galleries: those that display works by well-known artists, those of new artists, those that have been introduced and need to be continued to be introduced to become famous. The guide for us to tour the galleries in New York was female professor Sandra Lang, dean of the department of fine arts management at the University of New York. She said, a unique feature in the operation of galleries is that the director is responsible for close relationships with artists to select or order works for display. Americans often value reputation, so people always talk about the best of themselves or of their partners: the most prestigious, the most modern, the biggest, the most unique, the most geographical. the broadest, has the most connections to the world, and so on and so forth. That's why rich people in the US or in other countries come to the US to buy paintings often go to famous galleries. For that reason, artists want to display and sell their paintings at large galleries with famous collectors. And so a symbiotic couple was formed: art collector and artist. In order to carry out the task well, the gallery director must have good eyes to appraise the work, and at the same time must have good ears to hear the requirements of the market, creating a reputation for his gallery. The relationship between the gallery owner and the artist is very comfortable and fair: the hanging of paintings is agreed upon by both parties without any strings attached, usually hangs from 4 to 6 weeks, when sold, enjoys a ratio of 50/50 painting value. If they can't sell, the artist takes the painting back and doesn't have to pay for hanging the picture, nor does it receive "hanging profit." Although they have the same model, each gallery's operating method has its own unique features. According to the introduction of female professor Sandra Lang, there are up to 200 galleries in this area. We only visited 4 galleries.

The first gallery called DIE only exhibits paintings by artists who have stable careers and are famous. According to the introduction, the operation of this gallery is not for profit, but the entrance fee is 6 USD per person. The first floor of the gallery is divided into two rooms, both with art displays. The person in charge of this floor said that this house had just been renovated in a modern style and suitable for an art gallery. At this moment, the gallery is having a rather strange display: the entire ceiling of the two rooms on the first floor is covered with yellow and red silk strips running horizontally like a hammock, and there are strips hanging down the room. In some places, people hang down from the ceiling a microphone and on the floor opposite is a wooden pedestal. While wondering what kind of art this was, we were introduced to this place as a combination of art and technology. The instructor stood at a wooden platform, spoke a few words into the microphone, and immediately a sound echoed from the "silk domes" on the ceiling. These vague sounds combined with the strong colors and intricate patterns of the silk ribbons create an illusion of a mystical realm. However, it is difficult for us to have emotions with this type of art. The guide took us to the rooftop to "introduce a unique work of art". Standing on the towering rooftop, the wind was blowing, we were once again bewildered, wondering where that unique work of art was. The guide took us to the middle of the terrace, pointed to a glass "room" and said proudly: "This is a work that successfully combines art and technology. Glass panels are used to assemble the room." This room has different degrees of light refraction, so when you look out into the room, there will be surreal feelings!". While we carefully crept along the small corridor created by glass panels, the female tour guide continued: "At first, we ordered the author to display this work here for three months, but because of the price, we Its value was so strongly affirmed that we bought this work outright." I stood in the middle of the glass room and looked around, seeing nothing special. But when looking closely towards the West, seeing the glass printed with the image of rolling afternoon clouds and through that glass are the massive houses of New York, a magical feeling appears: the massive block of buildings. It's like floating on the clouds and I feel like I'm traveling in paradise! At this point, I believed in the female tour guide's recommendation. Certainly, at different hours, with different light intensities and sun angles, people standing in the glass room looking out will receive different images, creating different feelings. Please note the uniqueness of the exploration combining art and technology. We were instructed to follow the stairs rather than taking the elevator to go down gradually floor where you can see different galleries. I met a few teenagers carrying briefcases and brushes walking up. Perhaps it was an art student coming to practice. The next gallery, without a showcase, immediately saw its uniqueness: there were no paintings, but only five projectors that project images onto the floor and walls. That creates a vivid three-dimensional picture, on which is a golden autumn scene with bees flying. Seeing us admiring our praises, the tour guide excitedly: "The artist who creates a unique painting in this world is a female artist and engineer. It took her many years of research and creativity. But you need to note that even the wall and the other two windows, and also the natural light, make a complete picture like this. It takes many times to change the position of the 5 projectors to find the perfect harmony between the image in the movie and the real scene as you can see.When the light changes at different hours, this picture is also There are different nuances". At this point, I suddenly remembered a document from the FORD Foundation that mentioned America's love affair with technology. In the 20th century, movies, television, radio, phonographs and computers made up a very large proportion of popular culture. And now, technology has had a strong impact on drawing, which is a profession that has little to do with technology. America's love affair with technology will be even more intimate when it is manifested in the field of information technology in which the US is dominating.

The second gallery has a director named Max, a man with a sense of humor. He said one must be an art enthusiast to be a gallery owner. Mr. Max has been doing this job for 30 years, always collaborating closely with artists. The artists who hang their paintings here will not hang them anywhere else, but if they want to hang them somewhere else, they will have to go through him. That is also a management measure, not to saturate the painting market. Mr. Max confirmed that this is a commercial gallery, always thinking about profit. Paintings here are often large-sized and expressed in oil paint, with very high prices. For example, the painting hanging in the basement that we asked about is an oil painting about 2 meters wide by 2 and a half meters, painting a landscape, priced at 130,000 USD. Each year this gallery sells about 1,000 to 2,000 paintings.

The owner of the third gallery is a petite woman who has only been in the profession for 3 years. She has a master's degree in art management, graduated from the university of fine arts in 1997 from the University of New York and had a small exhibition displaying her works. The gallery focuses on the works of emerging artists, selecting contemporary and modern paintings that require viewers to think a lot. She said that the standard of the gallery is to choose artists that she likes and those who love the profession, and that her favorite is minimalism, which is a very simple type of painting, like the posters of the artist. Vietnam, with few lines and many colors, is like American cartoons. Artists who have exhibited here often introduce other artists to the gallery, as a result, the number of authors and works collaborating with the gallery is increasing. This gallery exclusively exhibits paintings by budding artists. However, these artists also have the right to display their paintings in other galleries inside and outside the United States. Asked about the total investment capital in the gallery, she said that it is impossible to calculate, because many investments, from real estate, the equipment to hang paintings in this room, to advertising measures to help artists design establish a market. The rent in this area is 50 USD per square foot per month, so the rent alone has to spend 120,000 USD a year. She told the truth that even if she wanted to, she couldn't afford to buy all the paintings here, so she just helped the artists establish the market. The price of paintings here is lower than in other galleries, usually 1,500 to 2,000 USD a picture, the cheap type even only a few hundred dollars, the expensive picture is only 5,000 USD, the most expensive painting sold is 25,000 USD. The reason the paintings here are cheap is because their authors are young, not famous, on the other hand, these paintings are different, viewers cannot understand right away to like them. The gallery owner turned her eyes to Professor Martin Suleman and said, "Even this professor said that the paintings here present a lot of challenges for the viewer, so he too cannot yet say whether they are beautiful or not, whether he likes them or not." Professor Martin Suleman interjected: "Whether it's for profit or not, in addition to money, there must also be a passion for art."

The fourth gallery has been operating for 40 years. The artists participating in the exhibition at this gallery are all famous people. We found that this gallery was displaying paintings by Alexander, which, according to the gallery director, was "between the abstract and the post-abstract school". These are large-sized oil paintings, some covering most of the front wall Draw a picture of groups of people standing and chatting in a garden. Next to it are a number of small-sized oil paintings hanging close together. The gallery director said that the price of this author's paintings is quite high, small ones cost 12,000 USD, large ones cost several hundred thousand USD. The gallery also has valuable works by deceased master painters, such as Picasso. Seeing that the painting was too large, I asked who could buy it, and the director replied: "We target customers who are companies, or collectors with large galleries." This gallery is open to everyone free of charge, including those who just come to look without the intention of buying the paintings. The director introduced himself as one of the most successful exhibitions in this area, and the reason for its success is that the owner always focuses on the artists. We know he is a highly professional, hired by the owner of the company to be in charge of this gallery. He has a warm and thoughtful attitude. Seeing that everyone was interested in the gallery introduction book, he said that it was a commercial publication, but could also be used as a gift, and promptly took out a few books to give to us. He told us that the reputation of the gallery will make the paintings sell at high prices. He told us that the owner of this gallery was initially a student in Boston, only had $10,000 to start the business, did not have enough money to hire workers, and had to mobilize his wife and children to hang paintings. That place sells paintings at low prices, only a few thousand dollars a painting, because the gallery is not yet famous, if left until now, it would have to sell several hundred thousand dollars a painting.

Through 4 galleries, I saw careful preparation for propaganda. Every gallery has advertising posters, catalogs, and even beautifully printed books introducing the works for sale. A common characteristic worth noting is the close relationship between gallery directors and artists, which is a symbiotic relationship, supporting each other in creative activities and profit, in which, to sell paintings at high prices, besides artistic value, there is also the decisive factor which is the reputation of the gallery. Perhaps in our country, it is difficult for any artist to accept a 50/50 split between the creator of the work and the seller of the work like this.
