# Tuniu (途牛旅游网)

> Tuniu is a leading online leisure travel company in China (NASDAQ: TOUR), headquartered in Nanjing. It sells packaged tours, self-guided tours, and travel products including hotels, flights, train tickets, cruises, visas, and local activities. Tuniu runs an Open Platform (途牛开放平台) exposing supplier and retail-partner integration APIs behind developer registration.

This file is generated by the API Evangelist enrichment pipeline from the Tuniu APIs.json profile. Tuniu publishes a partner-facing Open Platform; its technical API documentation sits behind developer login, so no public OpenAPI/AsyncAPI specification was harvested.
