Answer

最后一句用，meet with更简洁一些

Answer

xi'an -> Xi'an， 因为是专有名词

I also like to meet with my friends when I am free and I also like to be visited.

同意，应该说get together with my friends或者hang out with my friends

get together或者hang out的话，谁去看谁不清楚，所以不需要说and I also like to be visited，因为get together和hang out已经有这个意思

Answer

There are quite a few simple mistakes. 
Names and the start of a sentence should be capitalised.
Punctuation like commas and full stops (periods) should have exactly one space after them, and no spaces before. Please tell other people in China that this is necessary.
Grammatically, most of it is OK, except the last sentence. 'like' and 'visit' are present tense, 'was' is past. 
'be visited' doesn't make sense on it's own. Perhaps 'and I also like to be visited'.

Answer

yeah，thank you

Answer

A small note: The "friendly" form of the name David is usually spelled Davy (pronounced DAY-vee) -- at least in the USA.  Your spelling, "Davi", looks more middle-eastern and would be pronounced DAH-vee.
