When you say if should be Lee Ang, do you mean that the family name is Lee and should go first according to the Chinese rules?

That's right.

I see, thank you.

You're right about that. Though my name itself is quite short, being one of the vast majority of South Indians who don't have a last name, quite like Srinivasa Ramanujan, I was quite annoyed that my login id was based on my father's name, rather than mine, at one of the large companies I worked at. And, yes, I was a fussbudget until they fixed it.
