For traveling from Guangzhou to Dunhuang, we recommend train transfers: take a high-speed train to Xi'an North Station (6-7 hours) or Lanzhou West Station (7-8 hours), then transfer to a regular-speed train to Dunhuang Station (15/13 hours from Xi'an/Lanzhou, hard sleeper suggested). For convenient connections or personalized transport arrangements, we can assist with route planning and ticketing services. Contact service@intotravelchina.com for details.
