How do you say Hello in your language ?

Dear friends
love you all,
it’s my wish to wish you in your language . So pls pls tell me how do you say Hello ! In your language
as in Hindi-to seniors we say -Pranam !
Normaly we say -Namaste ! to wish any body.
I’d be thankful to you if you add how to say bye in your language.
In hindi -Phir milenge !
So what about your language friends ?

In Mexico we say  Hola como estas

In Vietnam, for informal (with friends) we use: Chào.

For the formal meeting (with seniors) we add the letter "Kính" before "Chào".

You see, Vietnamese is hard to pronounce cuz it has its rhythm. Many of our foreign friends indicate so. 

AAAAAAAAAA Hellllo

AAAAAAAAAA Hellllo

In portuguese (Brazil): Oi and Olá for every people, friends or no.

Xin chao from Viet Nam

I am from Kazakhstan and we say: Salem!
