Born following the adoption of the reform and opening up policy in 1978, China's post-80s generation was always going to play an important role in the nation's development. As the country's economy and confidence has grown, so too have they.

Fast food, Hollywood movies and the Internet are a major part of their lives -- they are connected and have their fingers on the world's pulse.

China's one-child family-planning policy came into effect more than 30 years ago and, according to a report in the Beijing Review, which quoted China Yearbook, an annual compilation of statistics published by central government agencies, 200 million babies were born between 1980 and 1989.

Yuan Yue, the president and CEO of consultancy group Horizon Research, said about 65 percent of the overall post-80s generation -- aged 20 to 29 -- were from one-child families, while that figure rose to 85 percent in urban areas.

During their advancing years, they have been branded spoilt, materialistic and self-centered, and accused of lacking a sense of social responsibility.

But those opinions have all but been reversed by an eventful 2008, a year in which they came under the spotlight not only during the worldwide Olympic torch relay, but also during the Beijing Games, and volunteered in their hundreds to boost earthquake relief efforts following the May 12 disaster in Sichuan Province.

Now many are dubbing them patriotic, persistent, caring and responsible. So which is the real post-80s generation?

The question has already grabbed the attention of the Brookings Institution, a United States think tank, which in April held a seminar on "Understanding China's 'angry youth': What does the future hold?" to examine this unique segment of society and discuss what makes them tick.

In the seminar's introductory notes, organizers said China's "angry youth", or fenqing, was a phenomenon for China and the rest of the world.

They also said that these 20-somethings often use the Internet to publicly express their views on politics and society, while their hyper-nationalistic and slightly anti-US sentiments, which started to emerge in the late 1990s, stand in sharp contrast to the Chinese youth of 20 years ago.

"We are a big part of the Chinese society and we have a real responsibility to react when our motherland is misrepresented," said Li Huan, a 27-year-old from Xi'an, Shaanxi Province.

Li made headlines last year with his patriotic and passionate speech at a Paris rally on April 19. Delivered in fluent French, he spoke before thousands of Chinese students and expatriates to support the Beijing Olympics and denounced the French media for distorted reports of the March 14 riots in Lhasa, capital of the Tibet Autonomous Region.

"The majority of the Chinese students at the rally were post-80s children," he told China Daily.

At the time of the speech, which was staged in the city's Place de la Republique, Li was a postgraduate student at the University of Lille II and has since been credited with helping to redefine the Western media's perspective on China's youth.

"After the April 19 rally, the French media for the first time reported on Tibet as a feudal serfdom society restricted by the Dalai Lama. It was the first fair reporting on Tibet after the Lhasa riots," he said.
