How to keep the show on the road when it's - 20 degrees

You need to be physically tough to work in Tsonyi county. It sits more than 5,000 meters above sea level in Nagqu prefecture of the Tibet autonomous region and the weather can be brutal.

At the Tsonyi county sub-branch of Agricultural Bank of China Ltd, only three of the 24 bank clerks are female. "Even the rocks in Tsonyi are male," Migmar Dradul, head of the Baingoin county sub-branch of the bank's regional office in Tibet, said.

Before he came to Baingoin in 2007, the 45-year-old worked as head of the Tsonyi county sub-branch for 10 years. He said the harsh environment there was too "hostile" for female employees.
