Yeshe Tenzin, the youngest ticket taker of the world highest Cypress Park, began to work at the park three years ago. He is in charge of guiding visitors in front of the gate and reminding visitors of those "DO NOT" signs.

The 25-year-old likes to smile , whenever checking tickets, answering questions or even telling visitors not to smoke inside the park.

Most tourists in Nyingchi will not miss the sight of "the oldest cypress tree" near the Bayi Township besides enjoying the natural scenery.

When we arrived, we saw Yeshe Tenzin right there introducing to visitors "King Cypress is more than 2600 years old…"

The park lies in the Baji Village of Nyingchi County, eight kilometers away from the Bayi township. The cypress trees are measured to cover ten hectares, with an average height of 44 meters and average diameter at the breast height of 1.58 meters.

"The park has the biggest cypress tree in China. The tree is fifty meters tall, with the diameter of at the breast height of as wide as 5.8 meters," Yeshe said. "It is said the tree is the life tree of Tonpa Shenrab, founder of Tibetan Bon religion."

There are eight people working in the park nowwith two people on duty  around the clock every day.

"In high season the cypress park basically receives five to six hundred visitor every day while in winter, at least ten people a day," one of his colleagues said.

Now there are over 900 cypresses in the park. Yeshe said that traditionally local people lived on cutting trees, but now timbering in the park has been explicitly prohibited.

"The government has made compensations to local woodchoppers," Yeshe explained.

Yeshe comes from Kongpo Gyamda, not far west of the Bayi Township, and his wife is a local in Bayi.

Just with primary school education, Yeshe said he had little trouble in doing his job. But he said that he would encourage his child, if he had one, to go to university.

As tourism is developing, local Nyingchi people have got more and more job opportunities. Yeshe said that he had been unemployed for years before he finally found a satisfying job at the Cypress Park.
