For everyone, please pay attention to hygiene.

Slogans like this are very characteristic of China. There are no examples to compare in English. It would be strange to translate them directly into English, because it is definitely Chinglish. Therefore, this situation requires a proper free translation of "hygiene". The concept of "hygiene" is too general. As you can see in the supermarket, hygiene refers to personal hygiene in English, such as brushing your teeth and washing your face, taking a bath and changing clothes frequently. Foreigners will find it funny when they see us promoting this, as if we China people are usually sloppy and need the government to promote personal hygiene. It is very funny. In fact, when we say "hygiene" in public, it mainly refers to spitting and littering, which are two unsanitary and uncivilized behaviors. This is the definition of "hygiene" in public that can be understood by both China and foreign countries. Therefore, this slogan can be divided into "No spitting" and "No littering". No Spitting! No Littering! Just do it. As for the expression "for everyone", there is no such expression in English. It is equally funny to add it forcibly, but it will not affect anything if it is omitted.
