When someone reply a comment,the person who receive the reply will receive a mail 有人回复评论时，被回复的人会收到一封提醒邮件
The plugin works and does what it says it does - the email is sent to the person leaving a comment.
However, the plugin does not support i18n, it's not possible to provide localized email text (it should adhere to https://codex.wordpress.org/I18n_for_WordPress_Developers). What's worse, the default language (i.e. the only language supported) is Chinese and not English.
Then there's one bug I found. The email is sent immediately after someone left a comment. That's wrong because it should only be sent once the comment is approved. Otherwise, the email says "look, there's a new comment, go to this URL" when in fact the new comment isn't published yet.
Also, the developer doesn't answer questions in the support forum.
