Jia Zhangke (born 24 May 1970) is a Chinese film director and screenwriter. He is generally regarded as a leading figure of the "Sixth Generation" movement of Chinese cinema, a group that also includes such figures as Wang Xiaoshuai, Lou Ye, Wang Quan'an and Zhang Yuan. Using only the above description and what you know about the world, "Lou Ye was excluded from the Sixth Generation movement." is definitely correct, incorrect, or inconclusive?
