Don't worry, there is a direct bus to Guanghua in Xingou at 7: 00 every morning. I used to go to Guanghua Middle School, and the Oilfield General Hospital was at the entrance of Guanghua, opposite the station. You can see it as soon as you stop.
Even if you get up late, you can go to Qianjiang first. There is a shuttle bus from Xingou to Qianjiang all day (10), and then there is a shuttle bus from Qianjiang to Guanghua (5), which is not slow.
Choose for yourself!
