With the support of the National Cultural Heritage Administration, the two-episode production of some 56 minutes traces the return of the two bronze heads and several other Chinese cultural relics from abroad, as well as the shared vision and cooperation between China and France in preserving historical legacies.

The documentary was also broadcast on the China Media Group's Documentary Channel on Friday and Saturday.

"For the past 11 years, these bronze heads from the Old Summer Palace have been carefully preserved and displayed in the museum, allowing millions of visitors from various countries to see them up close and appreciate the historical, cultural and artistic value behind these two treasures," said Gao Zheng, director of the National Museum of China, at the premiere.

Fran?ois-Henri Pinault echoes the sentiment. "The future is the door, and the past is the key to that door. Cultural heritage is not just the past … It's the key to the future, because if you want to build a better future, you need to understand the past. And to understand the past, you need to protect it and preserve it."
