Cheng embarked on a six-month trip to Europe in 1987, posting dispatches about it for the Minsheng Daily that were later collected into a book entitled Flying Solo to the Ends of the Earth. The trip also featured an afternoon tea with her future mother-in-law, a meeting that led to Cheng, much to her own surprise, becoming the wife of a German man several years later.
鄭華娟在 1987 年展開一趟為期半年的歐洲大旅行，旅程中一面為「民生報」撰寫專欄，最後集結成《往天涯的盡頭單飛》一書；也因為途中被「未來的婆婆」邀去喝下午茶，才在多年後誤打誤撞成了德國媳婦。
