How do you say "hello" and "bye" in your mother language?

hey! I want to know the difference between differents languages to say things

IT IS A QUIET GOOD  IDEA

IN ENGLISH THEY  SAY HI , HELLO

IN ARABIC WE SAY SALAAM ALAYKEM

In my country we usually say 'Halo' which refers to 'Hello' and 'Selamat Tinggal' or 'Sampai Jumpa' which refers to 'Bye'

Ukrainian version:

Hello - "Pryvit"

Bye – "Do pobachennya"or "Poka"

english word is  hello \bye

and chinese word nihao 你好\zaijian 再见

In spanish(Mexico) would be: 

Hello! -> Hola!, Qué onda?, Qué pex?, Qué rollo?

Bye! -> Adiós!, Nos vemos!, Hasta luego!

we  are say :你好（hello）, 再见（good bye）.

hi,

hello =  salam (it means: i wish peace & health for you)

bye = khoda hafez ( it means: I wish GOD protect you )

thanks for cool topic
