好耐冇見! hou2 loi6 mou5 gin3

你好 (néih hóu)
我叫做 ... (ngóh giujouh ...) ....IAIN ROSS (我叫...is more generally used; 我叫做/ 佢叫做/ 呢個叫做is more specific. You use that maybe you wanna emphasize its professional name/ nickname/ funny name)
好開心見到你 (hóu hòisàm gindóu néih) ( Just for more information: 見到你 means 'see you'; 識到你 means 'meet you' or ' get to know you')
拜拜 (bāaibaai) ( you can add: 下次見 = see you next time! or 聽日見 = see you tomorrow)

好開心見到你 (hóu hòisàm gindóu néih)

(or replace"開心"into"高興", it's the same)
拜拜 (bāaibaai)
