In fact, the World Expo that began in 1851 in London with the exhibition of industries was regarded as galleries of human inspirations and thoughts.
The concept of the World Expo combines not only political, economic and culture features, but it is also focused on demonstrating the latest stage of innovations in economic, social, cultural, scientific and technological fields.
In essence, this concept is all about exhibiting milestone achievements made by the human beings in various dimensions.
In a series of World Expo, the next expo is being held in Shanghai, China, which is slated  to kick off on May 1.
It is the first time, the mega global event is being held in any developing country. It also solidly establishes the fact that China has indeed made a quantum leap in almost every field, which has simply amazed and enthralled the entire international community. 
Nearly 140 episodes of World Expo have taken place in different parts of the world so far since its inception.
The Shangai Expo 2010, which will be participated in by 142 countries, will last for 184 days from its beginning. About 70 million people from both home country and abroad are expected to visit the expo to be run for the six-month period. 
The theme of the expo which reads "Better City, Better Life," represents the common wish of the entire humankind for a better living in terms of factors like basic facilities and environment, among others.
The theme sounds very pertinent in the light of the fact that over 55% of global population is living in cities, and the rate is growing at a rapid pace.
All the participants will exchange experiences of urban developments and explore new approaches and avenues pertaining to urban strategies and sustainable development to create eco-friendly society.
"The demand of better urban life is run throughout the history of human civilization" is the sub theme of the expo, which provides an extraordinary educational and entertaining platform for visitors.
The expo is gravitated towards blending of diverse cultures in the city to promote the harmonious coexistence as well as the integration of cultural identifications.
Likewise, it is also focused on economic prosperity in the city based on innovation and creativity of people, and the harmony of economic developments and environment.
The theme of the expo also advocates for innovations in science and technology in the city in conjunction with the protection of non-renewable resources, remodeling of communities with reasonable residents composing, housing ownership structure, improved infrastructure, pleasant accommodation and environment, sufficient employment and opportunities for establishing business, as well as profound social cohesion. The theme also suggests the harmonious developments between urban cities and rural areas.
Another major highlight of Shanghai Expo is the cross-culture dialogues, which are important for future's understanding, cooperation and development for the sake of greater good of the dwellers of this planet.
 Before the conclusion of the Exhibition, the Shanghai Declaration will be issued which will act as a spiritual legacy of urban development.
With some days remaining for the grand unveil of the World Expo 2010, China's financial capital Shanghai is looking to seize the limelight with its promises of incredible amount of glitz and glamour.
China is the first developing nation to host the World Expo and officials hope the event, will improve Shanghai's position as a global city.
Shanghai is doing its best to impress visitors with the city government already splashing out more than $700 million on renovating the Bund riverfront, as well a whopping $45 billion to upgrade transport and infrastructure.
Massive constructions of new metro lines have been undertaken for years in order to serve the traffic demands of the event.
While Shanghai is stripping hawkers and various eyesores off its streets, as Beijing did before the Olympics, the event is not targeted primarily for an international audience. Officials expect only 5 percent of their expected 70 million visitors to be from outside China.
And much of their tourism promotional efforts have been targeted at the potential of China's domestic tourists to make a trip to Shanghai for the Expo.
Officials acknowledge, however, that the showcase exhibition, complete with musical fountains from France and bratwurst sausage from Germany, will be beyond the means of many Chinese. 
Major attractions:
The activities of the Shangai Expo can be divided into three catalogs. The first is pavilions. There are more than 100 pavilions and the national pavilion day will be held on almost every day. Second catalog is cultural performances. There will be 100 performances every day and total number of performances will exceed 20,000 during the entire period of the expo.
Moreover, the participants of the expo will have their own events in their respective pavilions.
The third catalog is expo forums in which a summit forum will be organized, six thematic forums and more public forums will be held.
Theme Pavilions
There are five central theme pavilions at the Expo 2010, exploring different aspects of urban development. They are called Urban FootprintsUrban Planet,Urban DwellersUrban Beings, and Urban Dreams.
Some of the theme pavilions are located in a central exhibition building constructed by the Chinese hosts. Covering an area of 11.5 hectare, it is the largest structure of its kind in the history of world expositions. The total exhibition space of this building is 80,000 square meters.
Urban Footprints Pavilion
Concept and design for the Urban Footprints Pavilion were contributed by theShanghai Museum. The pavilion portrays the growth of the cities as a decisive factor for human progress over the ages. The exhibition consists of four segments. In three rooms, the "City Origins", "Urban Development", and "City Wisdom" are explored. The 3000-square-meters lobby is devoted to the "Ideal Fantasy City", showing both its Western and Eastern characteristics. The exhibition uses high tech installations as well as cultural relics loaned from international museums.
Urban Planet Pavilion
The Urban Planet pavilion is located in the central exhibition building on the Expo Axis. Concept and design were contributed by the German communication agency Triad Berlin Projektgesellschaft. The company, which had already designed a pavilion for the Expo 2000 in Hanover, won an international bidding contest against more than 150 competitors.
With its total floor space of 12,000 square meters, the Urban Planet pavilion addresses the complex processes marking urbanization. According to its designers, the scenography combines Western forms of artistic expression with ideas stemming from the Chinese Feng shui heritage. In Feng shui, dynamic processes of life may lead to harmony between the elements, but they can also unleash destructive forces. Building up on this idea, the exhibition is characterized by a dichotomous structure illustrating the two-faced character of the city as both a consumer of environment and as a place for innovation and technology in the service of an ecological renewal for the future.
Urban Dwellers Pavilion
The concept for the Urban Dwellers pavilion was contributed by the agency of the Dutch designer Herman Kossmann. The residents of modern cities are the focus of this exhibition. According to Kossmann, its guiding principle is the awareness that city planners have to address the urgent needs of their residents as "the prerequisite for the city&rsquos sustainable development."
In the Urban Dwellers pavilion, video clips narrate the exemplary stories of six real families. The continents are represented by their home cities of Paris(Europe), São Paulo (Latin America), Phoenix, Arizona (North America),Lijiang City (Asia), Melbourne (Oceania), and Ouagadougou (Africa). The circumstances of life of the six families are presented in five chapters concentrating on the issues of home, work, relationship, education, and health.
Urban Beings Pavilion
In the bidding contest for the Urban Beings pavilion, a joint proposal of theChina Central Academy of Fine Arts and of the Land Design Studio in London prevailed. The exhibition examines the growth of the infrastructure of modern cities, presenting the perplexing networks of both traffic and of water and energy supply as core elements in the urban "organism".
The exhibition rooms include a "Dynamic Station", reminiscent of the architecture of huge train stations in the early 20th century. Train models from different generations are presented here. Visitors will also walk through a "Circular Pipeline", where they find insight into the workings of that underground infrastructure of the city, which is usually hidden from their eyes.
Urban Dreams Pavilion
The Urban Dreams pavilion is located in a power plant of the early 20th century which was reconstructed for this event. The exhibition was designed by the Spanish agency Ingeniaqued in cooperation with the Chinese artist Bu Hua. The concept involves an imagined travel into the future, adopting an optimistic view of opportunies for developing hospitable cities via a combination of technological progress and tradition.
Visitors walking through five exhibition rooms will find examples of sustainable solutions for urban problems concerning living, traffic, energy supply, and city planning. There are specific references to innovations put into practice in such diverse cities as BeijingKōbeFreiburg im BreisgauCanberra and San Diego. The high point of the tour is an animated movie shown in a 35-meters-high hall. It presents a colorful fantasy world.
Nepal's participation
Nepal is set act an active participant in the Shangai Expo. Nepal pavilion is named Arniko Center to memorize Arniko, the famous Nepali architecture veteran's contribution to Nepal-China friendship. The Nepal pavilion, copying the style of Arniko times after 11 century, is an exquisite work of art with a large Buddhist pagoda at the centre, surrounded by several folk houses representing systems from different periods.
The government assigned the Implementing Expert Group, a professional institution working in making pavilion, to make preparation of Nepali pavilion. Nepal will showcase the country's culture, heritages, and tourism destinations during the event. According to Nepali organizer, it has invested around Rs.300 million (US$ 4 million) for preparation of pavilion. According to him, Nepal's Pavilion, covering floor space of 3, 600.
Nepal has planned to bring one million tourists in 2011 by announcing Nepal Tourism Year-2011.
With the Chinese tourist's arrivals picking up increasingly in the recent days, Nepal's fine-tuned efforts towards tourism promotion during the expo could be fruitful.
Nepali participants will distribute millions of leaflets printed in Chinese language during the expo in order to promote the image of Nepal in China.
About 10 million people are expected to visit Nepal pavilion and gather various information related to Nepal.
The proximity of Nepal pavilion with Chinese pavilion in terms of distance will also be helpful to promote tourism among a large number of potential Chinese tourists. 
China has emerged as the one of most lucrative tourism markets for Nepal with massive growth in the number of Chinese outbound tourists.
Moreover, it can be anticipated that the Nepal pavilion will also be able to draw the attention of millions of visitors from other countries that can eventually give a whole new boast to the Nepali Tourism Industry.
