Silk Road Sightseeings to & fro Dunhuang to Urumqi

Hi, Frankie! I think 2 days needs to be spent in Dunhuang and 2 days in Urumqi.
Here is the itinerary:
Day 1: Ancient Dunhuang Town, Thousand-Buddha Cave, Yumen Pass, Han Great Wall, and Demon Castle in Yadan.
Day 2: Mingshan Mountain and Mogao Caves. Take a night train to Liuyuan at 19:18 and transfer to a train to Urumqi.
Day 3: Heavenly Lake
Day 4: Tianshan Canyon.

Thanks Cecillia for the information but we are traveling on road we will stay in Dunhuang for 2 nights before our Xinjiang trip, the following is my proposed Itinerary after checking some of the road Riding Tour Package online.
Dunhuang to Loulan to Korla (overnight) to Turpan (2 nights) to Urumqi (2 nights) to Hami (Overnight) then back to Dunhuang or any other place yet to be decided
We will visit places recommended by you.

Thanks & Warmest Regards,
Frankie
