One value for multilangual page

Hello i have a multilangual website (8 languages)

And i have a template named ‘trip’, a trip have X days and X nights

For a trip that have for example : 10 days and 9 nights, i want to edit the value of Nights only once … and not have to change for the 8 languages each time. How can i do it ?

Thank you
