Local tourism is also developing thanks to the road upgrade.

Various businesses such as farm stays, pastoral stays, and guesthouses have begun to develop in Songde village.

"Currently, the new residential houses being built in the village will eventually be turned into guesthouses," Lo said. Once the houses are completed, villagers will invest by contributing their available rooms, with the government providing funding for renovation. The profits from the operations will be distributed according to the proportion of their investment.

Wei Changming, a local driver with over a decade of experience, highlighted the transportation transformation.

"Previously, many villages were inaccessible or required high-clearance vehicles. Now, the improved roads make travel much easier. I often transport passengers and packages from the county to the villages, with fees ranging from 2 to 10 yuan," he said.

These improvements in Rangtang county are part of a broader initiative to enhance rural infrastructure across China. Liu Changmei, deputy head of the county's transportation bureau, noted that the county's road network spans approximately 1,028 kilometers, with rural roads making up about 744 kilometers.

"In such mountainous and canyon-filled regions, the development of rural roads is crucial for overall growth," he said.
