Liu Jin is one of the young and active artists now. His latest art experiments are all used his body as medium. His opuses aspire after feelings of releasing for using his body with pleasant sensation of being presence in the foreland of art experiments. Although his opuses contain some behavior art, I slide over to say that his art exploration is only the behavior art, it doesn't mean that behavior art is the wicked way for artists to get high reputation and flubdub, also it doesn't mean that the actual behavior art is target of public criticism in the government art criticism circles, we can say that because of many people just pay their attention to the Chinese meaning of "behavior". For this reason, it is similar to the performing art.

刘瑾是目前较活跃的年轻艺术家之一，他最近的艺术实验均以自己的身体为媒介，他的作品追求身体在执行作品的过程中的释放感和在场于艺术实验前沿的亢奋，尽管他的作品包含了许多的行为艺术因素，但我还是回避了以行为艺术来简单化的指称他的艺术探索，这既非是行为艺术在某些人眼里已成为哗众取宠，沽名钓誉的恶俗行径，也不是因为目前行为艺术在官方的艺术批评界已成为众矢之的，而是因为行为艺术这一名词本身在中文语境中过于看中行为本身，在这一点上，又同表演艺术相差不远。
