confused abt shaving 🥹✌️

im planning on shaving my facial hair the next week, but i've heard you're supposed to shave in the direction of your hair growth (mine goes like towards my ears direction.) but a lot of videos i've watched for shaving (like tutorials and things you have to avoid while shaving.) shows them shaving only towards the mouths direction. like a lot of videos say thats the way you should shave? so should i shave from ear to mouth (directions, not literally hehe) or from mouth to ear? thank you sm if u read up until here :> it'd really help if i'd get an answer :D have a lovely dayy
