Transportation from Karamay to Urumqi?

About 400 kilometers away from Urumqi, in Chakoutou Town, Fuyun County, 2 16 National Road passes through Chakoutou Town, which is the only way from Urumqi to Altay and also a tourist area. There must be a bus, which takes more than five hours (I saw that it takes six hours for Urumqi to go to Fuyun County via Karamay), but it should be uncomfortable to take such a long bus. More than 30 degrees during the day in July and August is normal. Now the weather forecast for late June is 16-30 degrees.
