First notebook entry: Introducing myself

Hello. I wanna make friends with you. I can teach you Chinese and show you the local custom.

Hello! Welcome to italki! It's always good to learn more about Chinese culture.

First notebook entry: Introducing myself

Hello. I'd like to wanna make friends with you. ~I can teach you Chinese and~show you our local customs.

Hello! :) It already looks as if you've picked up a few bad English habits ("wanna", "u"), so I'll explain exactly what you mean when expressing your wishes:

I'd like to - this is standard for requests and wishes, and also polite. I strongly recommend using it.

I want to - this is stating a fact. In a request, it's a little too direct and pushy.

I wanna - this is considered illiterate (no, I'm not joking). When a native English speaker says "I wanna...", they sound poorly-educated and selfish. In a request, it sounds rude. I'm sorry that somebody thought this was OK to teach you.
