A policeman persuades Hou to climb down. The 36-year-old, who hails from Guangyuan in southwestern China's Sichuan Province, came to Xi'an after Spring Festival in February to take on a job as a woodworker on a construction site. One night several days ago, he was robbed nearby the Greater Wild Goose Pagoda and did not return home. From that fateful night on, he started losing his mind. [Photo/Takung.cn]
