(CHEN XIAOGEN)

A model of a Mars probe draws people's attention at an exhibition of China's key technological achievements from the past five years on March 8.

The exhibition, which began on March 7 at the China National Convention Center in Beijing, continued until March 14 and admission was free to the public.

A bullet train, a hybrid electric vehicle and a model of C919 plane—the first large passenger jet designed and built in China—were among the items on show, representing China's technological progress during the past five years.
