I want to thank a flight attendant on the train.

It's no use writing to him if you want to thank him sincerely. The best encouragement and help for him is to send him a banner.

K8 19 belongs to Chongqing Passenger Transport Section of Chengdu Railway Bureau.

Call the crew of Chongqing Passenger Transport Section, find the captain of this train team, tell him your boarding date, and ask him to help you check the name or work number of this flight attendant. You can deliver the pennant in person or mail it to their team.

When the team receives the pennant, it will praise the stewardess.
