Nanjing Suggestions for 2 - 3 days.

I arrive this Sunday night, and the next days 2 days are to explore. The plan is to stay at a hotel next to the Confucius temple.

My main mission is to hike at dawn, one day at Niushoushan Forestal Park and the other day for Purple mountain. Then, when it's too hot, go by public bicycle to other sights. (This is the map I'm using as reference). Let me know if you guys have any suggestion in general or for another sight to check out.
