About me (written in Chinese (traditional characters))

你好！我家有五個人。媽媽、爸爸、妹妹、弟弟和我。我媽媽是醫生。我今年學習漢字，我寫漢字很慢。

Hi I think this is better!

when we want to say a series of members or things  we will use "、＂between two words in Chinese.

And between last one and last second one you can use "和＂or＂以及＂.its same!

五＂口＂人: I think "口＂ is more formal but "個＂ is more oral speaking. 

今年我：its not wrong But it sounds weird! So "我今年＂ is better!

And when we talk about "漢字＂you don't have to say "中文"because 漢字 is Chinese word so you don't have to say  that , it sounds weird too.

i hope you can understand my poor English describe!
