Is it cost-effective to go to Jiuquan from Gulang by bus or by train?

It's cost-effective to take the train, take N85 1, that is, Du Liang, arrive at Gulang Station in the afternoon 12, take ticket 42, and arrive at Jiuquan at 7: 20 in the morning. If you don't want to take the bus at night, you can also take the 266 1 bus to Yongdeng, arrive at Yongdeng at 4: 00 during the day, and arrive at Jiuquan at night 12, with a ticket of 35.

Only on behalf of personal views, don't spray if you don't like it, thank you.
