Over the past decade, Shenzhen has become home to 190,000 returned students and two million technology professionals. "We have a lot of returned students. They're relatively commonplace. Out of six people in our department, four are returned students. In Shenzhen, high tech is developing fast. At this kind of start-up company there's bound to be work pressure. However, we still take time to enjoy life. We have our own way of relieving pressure," said Qi Shuyue, an Orbbec Technology employee.
