After Donald Trump became the 45th American president, a new video of his granddaughter Arabella went popular once again on the Internet. In this video, the little girl  wore a qipao, a kind of traditional Chinese dress. She stood in front of a table to recite(背诵)
ancient Chinese poems. These poems are familiar(熟悉的) to most Chinese people and they are often recited by Chinese kids. Arabella made the video to remember Chinese Monkey Year, which ended on January 27th, 2017.
Arabella’s family are interested in Chinese culture. They can even make Chinese dumplings and sing Chinese songs. Arabella began to study Chinese when she was 18 months old. Now she can speak very good Chinese. Early in February, 2016, 4-year-old Arabella, recited a Tang Dynasty poem in Chinese. Her mother sent her video online and won lots of “likes” from all over the world.
On Sonia Weibo, many users thought Arabella was a wonderful and surprising girl. “I’m glad to see the little angel(天使) loves Chinese culture,” wrote a user called “orange”.
