阅读下列短文，从下面每题的A、B、C、D四个选项中选出最佳答案。
C
Cultural relics (文物) carry rich history. But sometimes, they seem like something that only older people enjoy. Recently, a CCTV show about cultural relics has taken young people by storm. It's called National Treasure．
The show has been highly praised on Bilibili.com. This website is believed to be China's biggest pop culture website for young people. So how can a show about relics from hundreds or even thousands of years ago attract so many young viewers?
The show's 10 episodes (集) show 27 treasures from nine museums across China. Instead of telling the stories and history behind them, the show invites famous actors to act out these stories on stage．
Actor Wang Kai plays Emperor Qianlong on the show．He meets ancient artists, as well as his father, Emperor Yongzheng, in a dream．They criticize Qianlong's taste in such fancy designs. But Qianlong argues by saying that this kind of design is the best way to show the prosperity of his time.
This soon became a hot topic online. Screenshots of Wang Kai's performance were made into popular memes. Internet users also compared pictures of vases from the times of Qianlong (1736-1796) and Yongzheng (1678-1735)．
The stars might be part of the reason that young viewers enjoy the show. But it is still the treasures themselves that are the main focus. “The treasures make me so proud of our country and culture”, internet user “Fengshiyuci” wrote on Sina Weibo. “After watching the show, I want to visit all the museums in China,” wrote by another user with the screen name “Pilipalaxiong”．
