Fine answers, but don't forget there are a couple dialects of Chinese. Most of the answers are in Mandarin dialect that are spoken in most of mainland China, and Taiwan. But in Macau, Canton (on the mainland), and Hong Kong, folks speak Cantonese. Good bye in Cantonese sounds something like 'joy geen' and Thank you sounds something like 'daw jeh'. If you want to say: Hello, Beautiful, it sounds something like 'Nay ho, leng loy? (to a female)' or 'Nay ho, leng jai?' (to a male). [caution, pronunciations are calibrated for speakers of American English]
Hi si '你好'。Goodbye is '再见'。
To say "hi" in Chinese, you can say "你好" (pronounced "nǐ hǎo").
In Italian or in Italiano, "ciao come siete", means hello how are you.
just say hi, hiya, hola and to say goodbye say bye, bye-byes, or adios!
Hi in Chinese is ni hao of 你 好 which is pronounced nee how.
hi how are you i wash your okey ok thank you goodbye love you
You pronounce it "hi-zi" or "shou-hi"
你好
嗨 ni how
Nihao
In "crazy language" 'goodbye' means 'hello.'
喂,嗨 (hey hey) this is Chinese for hi
