In Xinjiang, an ancient water system still serves

The city's cultural heritage bureau has been using money received from the National Cultural Heritage Administration for preservation of the wells in recent years. More than 7 million yuan (around $1.1 million) has been used to repair and reinforce the karez irrigation system in Turpan this year.

"Protecting the wells is about preserving our history and culture," said Li Gang, a researcher. "The ancient irrigation system also helps boost the local tourism. We plan to renovate another 15 karez wells next year."
