Is Django session translation customization sticky for all languages ​​except Chinese?

Question

I have a really strange problem that I have never seen before. I am using Django 1.10.

I have several dictionary files:

/locale/fr/LC_MESSAGES/django.po
/locale/de/LC_MESSAGES/django.po
/locale/zh/LC_MESSAGES/django.po

Application strings are written in English. Dictionary files are completed and compiled into files mo.

I keep each user's preference in the field language UserProfile. When updating my profile, I apply language translation to the session.

# 'up' is a UserProfile object pertaining to the user
up.update(language=form.cleaned_data['language'])
translation.activate(up.language)
self.request.session[translation.LANGUAGE_SESSION_KEY] = up.language
return super(self, UpdateUserProfile).form_valid(form)

This is great for French and German. return superdisplays the form template in French / German, and then I can go to other pages and see the French / German text.

( "zh" ). return super ( ), , .
