Introduction to Lanjin Ancient Ferry: As the transportation chokepoint of the southwest, the "Lanjin Ancient Ferry" was originally only accessible by boat and raft, but it was gradually unable to meet the increasing needs of business travelers. Nowadays, the bridge over the river was newly built in recent years. Many people still walk across the bridge every day, just like the businessmen back then, and re-experience the long history of the Bonan Ancient Road.
