Every July and August, Pemashung, the sales manager of the Tibet Postal Hotel, sees many tourists from different cities gathering in Lhasa, capital of the Tibet autonomous region. That period, the best for sightseeing, is the peak season for Tibet's tourism industry.

Pemashung has noticed that the so-called "post-'90" generation -people born in the 1990s - has become the main force of this army of tourists.

"There is a sharp growth in the number of young visitors since July. More than 50 percent of the tourists are post-'90 generation," said Pemashung. "They want to experience Tibetan culture."
