For example if a back-end system generates an error in one language (say English) but I need to display it to the user in another language such as Cantonese.

比如说，如果后端系统用一种语言(假定是英语)生成了错误消息，但我需要用另一种语言显示给用户，如粤语。

Note: if there was an error in the steps above or you did not specify the correct language, WordPress will default back to English.

注意：如果在上述步骤中出现错误或者你未在wp - config . php中指定正确的语言，WordPress将会跳转回默认的英文显示。
