First, line dancing, literally, is a dance that dances in a row. It originated from American western country dance music in 1970s, also called swing dance. At first, I played the guitar and clapped my hands and danced. With the development of the times, I later integrated into the European court and Latin dance steps. The dance steps are diverse, novel and easy to learn. It is a kind of dance that can be enjoyed by both individuals and groups. In recent years, it has gradually attracted attention in Asia. In Hongkong, Taiwan Province, Japan, Singapore and other places, it has set off a craze, which is welcomed by all ages and can be said to be a dance suitable for all ages.

Line dancing has now grown to more than 3000 kinds. The biggest feature of line dancing is that the footwork has strict rules, which must be consistent with everyone, and the hand movements can be freely played. Each dance music has its own unique dance code. The arrangement of new dance music must be certified by the International Choreographer Association before it can be distributed and promoted around the world. Therefore, the same dance music is danced in the same way all over the world. Under this consistent dance standard, row dancers can enjoy the pleasure of becoming friends with the world's dances. Whenever a new dance music appears, professional choreographers certified by the Choreographers Association can teach students according to the new dance norms. With the emergence of new steps and dances, line dancing is always fresh. The Choreographer Association will also hold competitions all over the world, and the number of participants often breaks the Guinness World Record. This is one of the reasons why line dancing is widely spread all over the world.

Each dance segment of choreography can be composed of different cyclic rhythms, such as 32 beats, 48 beats or 64 beats. So the dance steps of each song are repeated in a specific cycle rhythm. In addition, the basic dance rules of each line dance are also divided into two directions and four directions to rotate alternately. Line dancing combines many social dance steps, such as cha-cha, rumba, mambo, cowboy and rock. Under the multiple combinations and changes of such dance elements, line dancing is simplified, which makes dancers jump out of their own personal style and completely belong to their own interpretation, adding to the attractive charm of line dancing.

As a new dance movement introduced to China, learning line dancing can not only learn elegant posture, but also relax the mood, relieve the nervous mood, easily achieve the effect of fitness and weight loss, and make life healthier and better.

Second, the fitness dance in Citizen Square was originally a popular square dance in the north, with gongs, drums and suona. Now it is very popular all over the country, dancing with the music that people like. This kind of dance not only combines jumping, dancing, twisting and noisy, but also has many characteristics of dancing, and incorporates China elements such as disco, yangko, folk dance and aerobics, which is especially suitable for community people to keep fit. The arrangement structure and form are basically similar to those of the choreographer. Anyone can arrange music, and music can also use any music, without restriction, as long as it is in tune. A set of square dances does not need the approval of any organization, as long as people can accept and like dancing, they can be arranged. Generally, square dance is a group dance, and everyone dances together in groups.
