A new trailer for the documentary "Years Are Here", which will be screened on May 28, has been released. This trailer features iconic moments from throughout the history of the People's Republic of China, including the country's founding ceremony, the return of Hong Kong to the motherland in 1997, and the 2008 Beijing Olympic Games. The film aims to help older generations relieve their common memories and allow younger generations to get to know the historical events they couldn't witness.
