。 I just came until now， but Ithank you for your great help。。。 you're a
big help for us。 you and jchen are great。。

I saw your post on jchen's profile, and I decided that I would help out.
Depending on what Chinese typing software you are using, you can type a "word" together. In my software, I just type huanying, and 欢迎 comes as the first choice. Those are the characters for "Welcome".

this is the meaning of this?520=wǔ èr líng=wǒ ài nǐ=我爱你=I love you, ohh, I c , thanks now, I know that. thanks a lot. you`re a good teacher!! ^_ ^

I saw your conversation with jchen, and I have an explanation.

88 is pronounced bā - bā, which sounds like "bye-bye". 8's also look like B's.
886 is "bā bā lìu", and is short for "bye-bye le". Le is a particle in chinese which is used at the end of sentences, often to indicate past tense.

It's Chinese "number speak", which evolved from text messages (SMS), it is much simpler to type numbers than chinese characters, so numbers that sound like words are used instead.

ex. 520 is a very popular one. 520=wǔ èr líng=wǒ ài nǐ=我爱你=I love you.
