when is the best time to see the water reflection of the rice terraces?

How is the accommodation in Yuangyang? I'd like to see sunrise and sunset.
When is a good time to visit Dongchuan Red Land? I'd like to see all the different colours, red, yellow and green. Is one day in Dongchuan Red Land enough or do I need to spend one night there?

I'd like to visit the following places:

Kumming - Stone forest
Lijiang, Shuhe Old Town, Tiger Leaping Gorge, Jade Snow Mountain, Blue Moon Valley the move on to Chengdu and Jiuzhaigou.
How long do you suggest I take?
