Near Xihai Town, Dayu Tribe began as a station for travelers, according to a National Development and Reform Commission case study published in 2021. The account describes it later as a cycling service base, with four stations expanded to nine. It records seventeen bicycle-rental clubs in Haiyan County and more than 8,500 bicycles at the time. The figures belong to the article’s reporting period, but they show how a roadside pause became a network of services organized around people moving through the county by bicycle.

Cycling Stations on the Edge of Xihai
A 2021 prefectural tourism account followed the growth of Dayu Tribe near Xihai from a simple stop into a cycling service base, with pastoral households joining a changing local economy.

A stop becomes a service base
Tourism reaches herding households
The same account says local herders found work at Dayu Tribe as visitor numbers grew. It describes a nearby farm, Heqing Pasture, adding food service, pastoral experiences, dairy-cow adoption and online sales to its livestock business. Cycling routes were extended, with leaders and medical personnel accompanying groups, while the site added lodging. These details show tourism woven into existing farms and local transport. Xihai’s surroundings can be read through these connections: a town, an expanding cycling network and pastoral households testing new ways to earn from the movement of visitors.
