What is tango?

Tango is a popular ballroom dance in the 20th century. It originated in America, but it has a lot of Spanish dance elements. It removes the waving arms and shaking shoulders of the earlier American dance, and has been processed according to the rules of ballroom dancing, adding some smooth sliding steps, which has now become an international standard dance. People in modern society dance this dance in order to relieve the physical and mental fatigue caused by fast-paced work.
