2011 is a special year to all the people in Shenzhen. The 26th World Universiade will be held in the city from August 12th to 23rd.

As we all know, “Start Here” is the slogan of this great event. Does anyone know that a new life of two giant pandas will start here as well?

Shenzhen is expecting the pair of pandas for the Summer Univcrsiade. The pandas, a male and a female from Wolong Panda Research Center in Sichuan Province, will be “universiade Pandas”, just like “Asian Games Pandas” and “Olympic Pandas”.
