Since China Railway Harbin Group operated the first photography-themed train in early January, approximately 1,000 passengers have taken photos on Train K5197, which runs between Harbin and Yabuli, the ski resort cluster hosting the snow sports at the Games.

Wearing colorful Chinese and European-style costumes, passengers can enjoy photoshoots in two train carriages that have been decorated in different themes: Ice and Snow Fairy Tale and Nordic Street.

The group selected employees with an affinity for photography, makeup and picture editing, forming a specialist team to provide free photography services to passengers.

Passengers aboard the train can book the service by scanning a QR code.

The group also actively invites passengers to participate in costume shows, immersing everyone in the fun.

When group employee Zhang Peng heard about the service, he immediately signed up.

"I am a trained chef, but also a photography enthusiast," said the 38-year-old. "Although I have taken numerous photos, I knew little about portrait photography."

To capture satisfactory pictures for passengers, Zhang used his spare time to learn from nearby photography studios, and extensively researched composition techniques online.

"When I get on the train carrying my camera, I communicate with the passengers in advance to understand their preferred photo styles, themes, specific scene requirements, poses and personal preferences," he said.

"After shooting, I also collect feedback from them to understand how satisfied they are with the service and photo quality and get suggestions for the shooting process, in order to identify issues promptly and make improvements," he added.
