Hi, two weeks are too long for these three places. There are many places can be added to this route. Rice noodle is a famous food in Kunming. You can get around the city to buy some Puer tea. Then get to Jiuxiang and Stone Forest. Take bus to Dali, visit Dali Ancient City, Cangshan Mountain (snow in Cangshan Mountain is a famous scene of this place), you can take cable car to the mountian top. Then go to the Three Pagada. After that go to take cruise on Erhai Lake. Shift to Lijiang by bus then. Lijiang Ancient City is a good place to get around. There is a bar street in it. Rent a vehicle to Jade Snow Mountain. Ask for the local guide if it is still available in winter and keep warm. Get back to Lijiang, you can go further north to Lugu Lake and then Shangri-La (Zhongdian). Lugu Lake in the morning is charming and Mosuo people is a special minority group there. Baima Snow Mountain, Yuliang Wan, Meili Snow Mountain and Songzanlin Monastery are all good place to visit in Zhongdian. Suggest you rent a car in Lijiang for 3 or 4 days to those places. That's to say, a good local guide is very important, who can also help you save some money. In December, Wa, Lisu, Dulong and Shui minorities may has some celebrations for their special festivals. Those above may take you some 12 days. If you still have time, you can visit Xishungbanna in Southern Yunan to experience subtropical scene, a good idea in winter, isn't. Anyway, good luck to you.
