Could anyone suggest a rounte of Guilin, Yangshuo, Kunming, Dali, Lijiang and Chengdu?

I have booked a flight from Australia to Guangzhou and returning from Chengdu in April next year. I am travelling with my husband and another couple. We would like to travel between these cities, visiting Guilin, Yanshuo, Kunming, Dali and Lijiang, before leaving from Chengdu. Could you help us to plan an itinerary, as regards modes of travel, and lengths of stay in each place? We have 3 weeks to travel. Is it possible to cruise from Yuanshuo to Guilin?
