hi John, thank you for answer.
but I mean: I have three posts,
one post only have english language,
one post only have chinese language,
one post only have deutsch language,
if my wordpress default language is english,I hope only have english language post can see,
if my wordpress default language is chinese,I hope only have chinese language post can see,
As in the following picture：

default language is english,
In theme’s home page,
only show have english language post,
It good, that I want.
but in post detail page,
As in the following picture：

all language post is show,that not I want.

So, the post detail page or other page can like home page only show have default language post?

Sorry, my english is very bad , but i hope you can understand i mean.
