阅读下列材料，从 A、B、C、D 四个选项中选出最佳答案。

Bill:（reading）“White like jade, bright as a mirror, thin as paper, sound like a bell.”

Mom: Is that for your Chinese story competition?

Bill: Yes. It describes porcelain（瓷器）in Jingdezhen, the “Porcelain Capital of the World”. You know porcelain is called china in English because it was first made in China!

Mom: Interesting!

Bill: Many cities in China have a long history of porcelain industry. They have created wonderful porcelain pieces.

Mom: Like Rongchang? We made a bowl in the workshop.

Bill:（smiling）Lots of fun. But that’s pottery（陶器）. Rongchang is called the “Pottery Capital of China”, with Yixing, Jianshui, and Qinzhou. Chinese pottery has a very long history. Porcelain develops from pottery.

Mom: Any differences?

Bill: Er...（searching online）The clay（粘土）is different. And porcelain is fired at a temperature above 1,200℃; pottery below 1,000℃.

Mom: But they look so similar.

Bill: They are called “Taoci” in Chinese. But porcelain feels harder and produces a clear sound.

Mom:（tapping a vase）Like this?

Bill:（nodding）It’s blue and white porcelain, one of the four famous types in Jingdezhen, together with linglong porcelain, famille rose porcelain and color-glazed porcelain.

Mom: Any others?

Bill: Many well-known types there, and also in other cities, like Dehua near ancient Quanzhou.

Mom: The Silk Road on the sea?

Bill: Yes. Dehua porcelain was mainly collected by Europeans at that time. Along with China’s silk and tea, porcelain was one of the first goods traveling around the world.

Mom: Chinese porcelain has deeply influenced the world porcelain industry.

Bill: This is also in my story. And I’m thinking about what else I can talk about.

Mom: How about some Chinese artists? They create priceless works and have students from all over the world. One of them said, “Color is universal. There is no barrier between cultural communications.”

Bill: Yes! For cultural communication, there is no barrier; for Chinese culture, I will be a carrier!

Mom: Excellent!

Bill: Thank you, Mom. How can I know that much like you? There’s still something unclear.

Mom: Visiting a porcelain museum?

Bill: Good idea!
