How does it work when I want to be on top of Taishan Mountain at Sunrise?

In October, I will be in Liujiayu Village at the Kung Fu school. It would be great to experience the sunrise in the morning. My free time will be on the Saturdays from 11:30 and the whole Sunday. On the internet I found that the sunrise is at approximately 06:00. To ascend te mountain takes six, or seven hours.
Is it save to ascend at nighttime? I really want to see the sunrise. Please expand on my question.

Thanks in advance and kind regards,
Mark
