First notebook entry: Introducing myself

您好，我学习的中国人！我是一个新手，所以它可能需要一些时间。

您好，中国人！我正在学习中文，我是一个新手，所以我可能需要一些时间。

1  I guess you want to express such meaning: hello Chinese, whom I am learning from.

but in Chinese we do not set a long attribute clause before a noun.

2  You should say you are learning Chinese language instead of learning from Chinese people.

3  It need some time for me to learn Chinese. this can also write as "I need some time to ......". Chinese people will think in this way. you should not change the subject too quickly.

here is the native expression:

您好！我正在学习中文. 我是一个新手，所以可能需要一些时间。
