What is the name of the dance where many beautiful women hold hands and kick their legs together nothing?

It's called the cancan.

The Konkan dance originated in France and was originally a kind of light and rough dance. Usually performed by four women, it was a form of song and dance for working women such as laundresses and seamstresses. Later, it became popular in cabarets. High-Kicks, typical of the cancan dance, is a difficult maneuver that involves kicking the leg straight up to the ear. It is not a casual kick, but must be done above the tip of the nose. The way dancers practice this move is usually to prepare a balloon and hang it at the door, and practice until the kick reaches the balloon. A professional cancan dancer kicks no less than 1,500 times a week, and this kind of kicking does not only cause soreness and strain of the leg muscles, but also affects the back muscles. Another cancan move is to jump up and do a floor split.

The dance was originally popular among the working class, but by the mid-1800s, the cancan had become so popular that men began to dance it as well, incorporating it into other stage shows. The original meaning of the word "cancan" is scandal. The artist Henri Toulouse-Lautrec painted many beautiful paintings on the theme of the cancan, and the most famous composer of the cancan was Jacques Offenbach. The movie Moulin Rouge shows the history of the origins of the cancan, which was inaugurated at the Moulin Rouge on October 6, 1858, when the short, moustachioed, clownish master of ceremonies announced: "How beautiful life is, and now we invite you to enjoy the cancan!" As he spoke, twelve cancan dancers appeared. That opening line would later become famous in Paris. From then on, the passionate dance, the unrestrained rhythm, the difficult movements, the luxurious and eye-catching costumes, the colorful feathers, the lacy dresses, the beautiful dancers and the enthusiastic cheers, night after night, made the spectators off-stage blood boiling and intoxicated. At the end of the nineteenth century, the Moulin Rouge in the Montmartre district of Paris was once again famous for its thigh-baring cancan dances. The Moulin Rouge was a place where everyone, rich and poor, smart and stupid, came to indulge in the glamorous and decadent colors of prostitution and johns, drugs and alcohol, artists seeking inspiration, and a constant stream of tourists. With its lush color palette and over-the-top dance scenes, French Concours depicts the events leading up to and following the establishment of the Moulin Rouge nightclub in the Montmartre region of France. The cancan is now performed in Paris on the first Tuesday night of every month in cabaret nightclubs, and in 1860 it was introduced to England and officially named the "French cancan". The dancers move their bodies to the music and occasionally split their legs, revealing stockings and skirts. It is said that this style of dance is a kind of confrontation and rebellion against the conservative and reserved traditional social dance. English gentlemen had protested en masse, and English dance halls had issued expulsion orders against it. However, the conga was popular in Paris, increasingly popularized and became a splendid sight in Parisian cabarets and cafes. With the classic cry of the famous painter Toulouse-Lautrec: "How wonderful life is! Here comes the French cancan!" Cancan has been popular all over the world since then, from simple and rough to exquisite and luxurious, always new and unfailing for a hundred years. To this day, as the French Moulin Rouge must be performed every day program, attracting tourists from all over the world to watch and linger.
