The big dance group originated in a korean comic book audition, a game developed by t3 entertainment, yedang online in charge of its global distribution. It was first tested in korea in 2005 and has since evolved globally. The dance group is a free dance network game with a prototype similar to an online dance machine. Follow the music beat, click the corresponding arrows on the screen, and when the action is completed, the virtual characters in the game jump out of different dance moves. Virtual cash systems are used to sell virtual role costumes, faces, accessories, etc., and to provide some functional props, most of which require cash to purchase a virtual currency. In july 2005, the strong dance group became a priority for the ministry of culture of the people's republic of china to distribute online games for minors in mainland china. The strong dance group was developed by the korean t3 entertainment company, and the mainland china region is temporarily represented by jiuji. "...
