歌剧中的女孩是两种不同文化相遇的结果。阿根廷人的一个年轻女孩，沉迷于音乐戏剧，参观了悦来茶馆，对川剧的古老艺术着迷。通过对这个传统地方的多次访问，她不仅了解了歌剧艺术家的日常生活，还了解了岳来茶馆游客的日常生活，岳来茶馆是成都缓慢生活方式的象征。然而，书名中的女孩并不是这个年轻的女孩，而是一个小女孩——两位歌剧艺术家的女儿——她的出现将在外国游客中引发一些关于她对音乐戏剧的热爱以及传统艺术如何能传给年轻一代的问题。

The girl at the Opera is the result of the encounter of two different cultures. An Argentinean young girl, obsessed with musical theater, visits Yuelai Tea House and is fascinated by the ancient art of Sichuan Opera. Through her many visits to this traditional place, she not only gets to know the routines of the Opera artists, but also those of Yuelai Tea House goers, a symbol of Chengdu’s slow lifestyle. However, the girl from the title is not this young girl, but a little child – the daughter of two Opera artists – whose presence will spark in the foreign visitor some questions regarding her love of musical theater and how traditional arts can be transmitted to younger generations.
