The two organize various activities to interact with fans. They have held a photography contest for their followers, and they collect travel stories of fans and record them for their radio program.

They make marketing campaigns for destinations, such as inviting fans to travel with them and then having a sharing saloon. They also write advertorials on WeChat, around 30,000 yuan ($4,300) for a lead article.

Pang says top influencers in the travel field must be diligent, capable of enduring hardships and ready to work hard under pressure.

"They are often versatile－taking photos, editing videos, writing good articles and with a good taste in music. They are social butterflies who know how to cultivate extensive connections. They are open-minded and can keep pace with new trends, and express their values via their work," she says.

She adds that the current trends for presenting their travels are streaming and short videos.
