Inside Shanghai's robot bank: China opens world's first human-free branch

'Little Dragon' can chat to customers, accept bank cards and check accounts. She joins a growing army of robot workers in China's cities

Xiao Long, the latest employee at the Jiujiang Road branch of the China Construction Bank is never late for work. "Welcome to China Construction Bank," she chirps to customers arriving at the Shanghai branch, flashing her white teeth. "What can I help you with today?"

Xiao Long, or "Little Dragon", is not your typical employee - she's a robot at China's first fully automated, human-free bank branch.
