Since then, Politi has visited Yunnan every year, staying at his friend's home in Taiping town in Kunming, the provincial capital. Although Politi doesn't speak much Mandarin, he still greets his friend's neighbors every time he sees them. During his stays, Politi explores the province with Huang Linwu, director of the Yunnan Tourism Development Committee, who Politi befriended at the tourism mart.

"He has become so familiar with Yunnan culture that we often joke how he is a Yunnan native born in Italy," Huang said.

At the Long Street Banquet, a traditional Jingpo ethnic festival in Yunnan, Politi danced with the locals, wearing a white fez with stars and fur beads. Later, he put on a Jingpo jacket and ate from a basket full of traditional Yunnan food with friends.

Politi said the good weather, clean air and fresh food in Yunnan have worked wonders for his diabetes and hypertension. "But I love the kind inhabitants the most," he said.

Once, during a rainstorm, Politi's car was stuck in mud near a village in Lyuchun county. Local villagers rushed to help and afterward, they declined Politi's offer of money, saying "it is only natural to help others".

"People here are so nice, so welcoming. I wish to do something for them, for the economy," Politi said. In 2013, he became the international marketing adviser for the Yunnan provincial tourism committee, promoting the province on the world stage.

In 2014, the first direct air route between Paris and Kunming was opened. When packing for Yunnan's tourism promotion event in Europe, Politi removed his personal belongings to make room for more pamphlets. At the event, he used fluent Italian and French to introduce Yunnan to travel agents.
