The first clip is from American movie "Shall We Dance?". There was a Japanese movie prior to this one. The best part of the movie, to my point of view, is this 3 minutes of dance.
The second clip is from mivie "Take the Lead". I have not seen it yet.
舞蹈是动态的构图和雕塑,专业舞者经过训练,已经不需要花心思记动作,日臻熟练以后,则可以做到忘记周围一切,进入状态。探戈是两个人之间的高度默契,一致投入,充满激情, 犹如做爱的艺术, 要有专注的的引力和反引力, 要么不做,要做的前提一定是2个人的相互欣赏爱恋。如果单单为了释放生理压力,性如入厕,则宁缺毋滥。
