Business manner (urgent 10 points)

Usually only British use "How do you do?" If you use "How do you do?" when greeting Americans, they will understand, but they are not used to it.

At a formal meeting, when it's your first time meeting that person, after someone else introduced your names, you could say either "How do you do?" or "Nice to meet you". And if you and the person you just met have a conversation and one of you has to leave, then you could say, "Nice to meet you" or "It's great meeting (or chatting with) you".

Honestly, just maintain a polite attitude and people will understand that English is not your first language, don't need to be nervous about it's a "formal meeting".

How do you do means 你做得怎樣

Nice to meet you means 很高與認識你

If you attend a meeting, and that person is you first time meet, you should use NICE TO

MEET YOU.If that person that you have met before, you should use HOW DO YOU DO
