Hi Lenka,

I'm Joel Lee from Malaysia (like both of them on top).

there are basically 4 tones for mandarin words. I have included a simple guide in a file called 4 tones (which you will get a link to download at the end of this)

*This link also teaches you how to pronounce some of the things i shown below.

1. Can you hear me?
你听见我吗?
(ni3 ting1 jian4 wo3 ma1)

2. Hold me
In mandarin, the closest equivalent would me "hug me" or "hug me tightly". A literal hold me would be almost like "grab me" or something.
抱紧我
