Once the new road to the county town is completed, the old road will inevitably be abandoned, and the people of Sancha River town wanting to take a ride on the new road will end up having to travel a few kilometers farther. However, the new road is closer to Yan Fei's grandfather's house. It passes not far from their village, which includes Yan Fei's old home.
Which means if in the future one wants to travel from the town to the county via the new road, it would turn out to be a trip ten kilometers longer. The original distance was just over ten kilometers. Now it's going to be more than twenty kilometers to reach the county town, making the small town seem even more remote.
