You must have read or heard of Jia Baoyu and Lin Daiyu. The     16     between them is very painful. But can you imagine the two singing opera in English instead of speaking poetic Chinese?

Jia and Lin are two     17     from the classic Chinese novel Dream of the Red Chamber (《红楼梦》), which was considered to be written by Cao Xueqin, a novel     18    . Now the book has been     19     into an English-language opera. The opera was first     20     in September, 2016 in San Francisco, U. S. In 2017, it came to Beijing, Changsha and Wuhan. The book has 120 chapters (章) and several hundred characters. But the opera writer David Henry Hwang cut     21     the number of main characters to just seven. Hwang, a Chinese-American, focused     22     the love story between Jia and Lin and tried to write a heartbreaking tragedy (悲剧) that everyone would understand.

The art     23     Timmy Yip compared Lin to water and gave her a light green costume. When Lin shows up on stage, there is usually water around     24     on the stage.

The creators consider it to be a(n)     25     job to introduce a Chinese classic to Western audience (观众).
