In order to appeal to more young audiences with an easygoing style, Si says the crew paid more attention to specially selected relics with interesting stories.

For instance, in the last episode on the National Museum of China, a veteran guide introduces a less-noticed detail of the national flag raised in Tian'anmen Square during the country's 1949 founding ceremony. One angle of the biggest five-pointed yellow star had to stitch two pieces of cloth together as tailors failed to purchase an entire piece even after visiting all the stores in Beijing.

"If you could discover this detail, it will not be difficult for you to picture how hard and tough conditions were for the Chinese people before the founding of the People's Republic of China," says Si.

Wang Chao, a cultural relic expert who works at China Cultural Heritage Newspaper, says relics and heritage help historians to conduct research as well as stir up national pride of ordinary visitors.

"As early as in 1932, the Party made regulations about the protection and collection of such artifacts and relics, indicating China has attached great importance to the reservation of revolutionary relics for a long time." says Wang.

All these relics reveal the epic chapters in the history that the CPC and Chinese people fought for today's peace and prosperity, always reminding us to respect the legacies and inherit their spirit to build a better future, concludes Wang.
