A group of around 150 people now provide guide services in six languages to tourists who visit the famed Mogao Grottoes

Bian Lei is 31 years old, and he has visited the Mogao Grottoes, a 1,600-year-old UNESCO World Heritage Site in Dunhuang, Gansu province, more than 5,500 times over the last decade.

As a professional guide at the site, he walks tourists around the many Buddhist sculptures and frescoes there every day.

In his career as a guide, there have been moments when he has had to hold down drunken men while talking about the relics, and when devout Buddhists would go down on their knees and offer flowers and oil at the site, which is not encouraged by management rules.

There were also moments when he has had to describe the shape and color of the statues to the blind; and when a college professor told him: "I am jealous of you because you have the chance to spend so much time with those 1,000-year-old relics every day."

In peak season, which spans from July to September, he serves about 100 people a day, from 8 am to 6 pm daily.

His monthly salary is about 3,000 yuan ($436), lower than the average wage in Gansu. But Bian says: "I don't think I can find any job better than this one.

"I feel proud of my job. It's meaningful," he adds.

The Mogao Grottoes feature a huge collection of Buddhist art, including more than 2,400 sculptures and 45,000 square meters of frescoes in 735 caves dating back to between 40 and 14 BC.

There are frescoes depicting music bands and dancers performing at a royal court, and flying creatures playing three-stringed lutes known as pipa, among other scenes.

Many of the relics look vivid with well-preserved color due to the dry weather and low rainfall in Gansu.
