You must face honestly意思
"You must face honestly" is not a complete sentence in English and may be missing some context or words to fully understand its meaning. However, if we assume it is part of a sentence or instruction, "face honestly" could mean to confront or deal with something in a truthful and straightforward manner, without trying to deceive oneself or others.
For example, if someone were to say, "You must face your fears honestly," they would be encouraging you to acknowledge your fears directly and to deal with them in a way that is open and truthful, rather than avoiding them or trying to pretend they don't exist.
In any case, the context in which the phrase is used would greatly influence its precise meaning.
