Yuen Ren Chao (趙元任 Pinyin: Zhào Yuánrèn; WG: Chao Yüan-jen; Gwoyeu Romatzyh: Jaw Yuanrenn) (November 3, 1892 - February 25, 1982) was a Chinese phonologist and dialectologist who shaped Gwoyeu Romatzyh. ...

She is the author of two notable books: How to Cook and Eat in Chinese, and An Autobiography of a Chinese Woman.

In "How to Cook and Eat in Chinese", she has collected over two hundred and thirty recipes. Some came from her travels with Yuen Ren. He collected dialect data from across Chinese and often they stayed with their language informants. It was during these opportunities that Buwei would enquire about the dishes that their informants cooked. She write that though the recipes were not written down, she often recreated them from memory of their taste. Her "author's note " illustrates her family life with good humour and candour, also shedding some light on the great linguist himself, from his closest companion.

Buwei and Yuen Ren lived in Cambridge, Massachusetts when she was writing her recipes. As her husband was also involved intimately with the Harvard-Yenching Institute, she writes of contributions to her life from the wives of other prominent academics because of social interaction with her prominent husband.

In her second book, "An Autobiography of a Chinese Woman" she details the eventful life she has led prior to her meeting YuenRen, and afterwards in their travels together. Both books were published by The John Day Company, New York.
