After four years of hard work and waiting, Chinese Olympians are gearing up for athletic breakthroughs as well as a clean campaign at the 2016 Rio de Janeiro Olympics next month.

China announced on Monday that it will send 416 athletes, including 35 Olympic champions - its largest athletic delegation ever for an overseas Olympics - and it pledged to compete with full efforts against doping.

The delegation is made up of 160 men and 256 women. They will compete in 210 events of 26 sports at the Games, which open on Aug 5 in Brazil.
