Advertising is my occupation, but UFO research is my real career .... You wouldn't guess that Zhang Jingping owned a thriving private advertising company. He's got employees split up into two teams - TV and newspaper advertising. Not that they see that much of their boss. That's because in every spare minute, he returns to researching his pet subject: UFOs.
"I devote most of my energy and time to my research. My manager takes care of daily affairs of the company," Zhang explains.
