Hong Kong's former top delegate to China's legislature said Wednesday's military parade in Beijing sends a message to the world that the country has the ability to defend and protect itself.

Tam Yiu-chung was among 360 people from the SAR attending events commemorating the 80th anniversary of the victory in the Chinese People's War of Resistance against Japanese Aggression and the World Anti-Fascist War.

The former National People's Congress Standing Committee member told an RTHK radio programme the parade was very significant to not just the nation, but also the world - as it emphasised the victory was hard-won and that all people should treasure peace.

It also sends a message that everyone should work on building a future, instead of perpetuating hatred, Tam said.

"In the past... we got bullied and attacked because we were weak," he said.

"But now we are not. We won't invade or attack others. We have the ability to defend and protect our nation's unity and territorial integrity.

"But at the same time, we are very willing to promote and join hands with various countries to build a community with a shared future for mankind."

Tam, now the vice chairman of the Chinese Association of Hong Kong and Macau Studies, noted the SAR delegation this time consisted of 75 more members than a decade ago.

"This has demonstrated the central government's care, trust and support towards Hong Kong and Macau compatriots," he said.

"Whenever there are significant and important events, they will try to let us participate. It's good to let everyone to be there to experience it.

"Of course, it is very clear to watch it in front of the TV. We were watching it from one angle at the scene, but it was showed in various angles on TV and it was much closer by zooming in. But by being there to feel the atmosphere, it's quite touching."

For his part, Scientia Secondary School principal Wong Ching-yung said the school broadcast the parade live on campus to more than 1,000 people, including staff, students and parents.

He said history was very much in the minds of most students.

The school also held sessions to discuss and reflect on the nation's strengths, as well as the history of the war.
