Ye Chaohuan learned with interest that after years of construction, the urban area of Linköping presents an inverted "V" shaped layout in terms of geographical form.

A large blank area in the center is a nature reserve converted from a former military training area, and there is a large oak forest in the reserve. This blank space greatly hinders the transportation links between the eastern and western parts of the city.

For this reason, the city's recent plans to continue to expand the southeast wing of the city have drawn criticism. Critics argue that such a plan would lead to the fragmentation of the city, with residential areas to the southeast, industrial and commercial areas to the north, and university districts to the inaccessible west.

The greenery and park construction in the city of Linköping is relatively well built and well laid out, making it very accessible to most residents.

The large park "Garden Society" is located in the heart of the central city, and the "Rydsskogen" and "Valla skogen" forests were previously nature reserves.

However, the proposed "thoroughfare" or "Walla road" through the Walla Forest to improve traffic in the east and west of the city has been debated and has not yet been decided.

In September 1996, after a severe fire, the Linköping Library building's more than 700-year history came to an unsatisfactory end. Shortly thereafter, however, a new library building was rebuilt on its original site and reopened to patrons in March 2000.

The new library building does not follow the tradition, but adopts a bright and modern architectural style. This makes the building stand out.

Other important cultural facilities and groups in the city include the Stedelijörk Ostjötland County Museum, the Ostjotta Theatre, where the youth choir often performs, the Gallery of the Arts and the Linköping Symphony Orchestra. Lin Xueping has cultivated many choral groups with high attainments and can be called the national level.

Many famous musical artists or groups have started their careers at a famous music venue called "Skylten" near Linköping train station. Among them that became famous were Rush Winné, Louise Hoffsten, Pusjkins and Cloudberry.

In Linköping, citizens can also visit the Fun Skate Park. This is currently the largest concrete skating rink in the Nordic countries. High-level international skating competitions are often held here.

Linköping's city newspaper, East Jota Newsletter: Corren, was first published in 1838. The newspaper's circulation covers the western part of the province of Gottland. There used to be another daily newspaper in the city, Ojötjot, which was owned by the Swedish Social Democratic Party but ceased operation in the early 90s.

The local TV channel, NollEttan, was born out of an information channel co-founded between 1996 and 1997 by the city's social housing company and the city's energy company.

The channel now broadcasts local sports, news and more. Initially, the channel's coverage was limited to Linköping, but many years later, the channel's coverage has expanded to cover the entire province of Ötjotland Province.

Linköping has had all the elements of an academic city since the church facilities were built locally.

Today, the city remains one of the largest university towns in Sweden. Linköping University currently has more than 28,000 students and is one of Sweden's largest national universities.

The university also has a campus in the neighbouring city of Norrköping (Linköping Campus) and a US campus (University Hospital Campus) with a medical school and a Campus Valla campus as the university's main campus.

Linköping also had a number of "higher schools", such as the Linköping Cathedral School, which was built in 1627, the National Youth School, Anders Yonstedt High School, and the Berzilius School. The representative school of other educational models is the National Technical College of Vala.

Linköping University ......

Linköping University is a national university in Sweden.

Linköping University was founded as an independent college in 1960, was approved as a university by the government in 1975, and began to establish a Norrköping campus in the neighboring city of Norrköping in the nineties.

Linköping University has three faculties: the Faculty of Technology, the Faculty of Medicine, and the Faculty of Liberal Arts. Its Polytechnic is usually open to students under the name "Linköping Polytechnic (LITH, established in 1969)", and its medical faculty was merged and restructured from the "Medical University" in the 80s.

In addition, the university actually has a de facto separate faculty of education, but there is no formal administrative structure of a separate college.

In 2005, the university had about 28,000 students and 3,500 faculty members. Linköping University is one of Sweden's largest institutions of higher learning, and most of the students attending classes at Linköping live in the university's student residence complex in the Linköping district of Linköping.

Linköping University's motto is "Expanding Reality".

Linköping is the cradle of the Swedish Air Force.

The Carl Sedström Flying School, built in Malham in 1912, was the forerunner of today's Malham F3 Air Base. Saab Aerospace was founded in Linköping in 1937 and began to design and manufacture aircraft.

Today, the Malham district houses the Aviation Weapons Museum and the "East York Helicopter Base".

Other military facilities located in the local area include "T1 Barracks", artillery barracks A1, I4, I5, Lv2, etc. The garrison has a dedicated area in the city's new town, while the old barracks are being used for other purposes.

There is also a garrison museum outside the garrison.

The Air Force Museum is located in Linköping, Sweden's famous fighter and commercial aircraft manufacturing site. Everyone who comes here will be attracted by the plane hanging from the ceiling, and the sound of admiration will be endless.

It could be a Ba-nana, or the Vampire, or the Draken. More than 50 models and entities of Swedish fighter jets introduce the history of the Swedish Air Force in detail to visitors.

From the Swedish JAS-39 Gripen fighter jet, which represents the world's leading level, to the wreckage of the DC-3 plane shot down by Russia in the Baltic Sea in 1952, from the entertaining and educational flying laboratory to the films, photos and materials that reflect the history of aircraft development, this is simply a paradise for flight fans.

Most of Linköping's companies are in the technology industry.

Among them, Saab is the largest company in the country with about 4,900 employees (as of 2003).

The well-known telephone company Ericsson employs about 1,100 people at its GSM mobile phone factory in the city (2003). In addition, there are some more important consumer goods manufacturing enterprises in the city, such as Arla, Scan, etc. 19
