Addicts do group exercises at a drug rehabilitation center in Anhui province, June 19, 2013. "The days when I took drugs, I changed a lot in temper and became crusty and paranoid. After a year of drug control in the center, I've shrugged off many bad habits and become much better in body and mentality. Now I'm eager to find a job in my hometown after my drug control ends and spend more time with my family," said one drug addict. There are 500 addicts at the drug rehab center, which provides them with medical treatment, psychological counseling as well as skill training to help them return to society. [Photo/Xinhua]

A film crew captures pictures of Tibetan antelopes crossing a construction site on the Qinghai-Tibet Highway in early June, 2013. The site, which is an important passage for the migration of the antelopes from the Sanjiangyuan Nature Reserve, will build an elevated bridge for vehicles in order to leave a safe underpass for the animals. The Tibetan antelopes migrate once a year around June to their breeding grounds. [Photo/CFP]
