Chinese Government?

I think you may choose to write about Chinese Government.

1) Unique is important! If your presentation is similar to others', then isn't it quite boring? Besides, if your topic is special, it will become more eye-catching.

2) China is a place almost everyone knows. The Government of china always show up on TV. Especially in US, people would like to know more about foreign government.

3) I think you come from China, right? Then just talk about your birthplace's government!

Hope i can help you!

I think the best to write is united states's government or president
you can find their information easily on the web
i hope this helps you^^

The ease of writing any topics depends heavily on how much you are familiar with the topic and how much information you can get from research. It is very difficult to determine. It may be easier if you write about the environment you grow up with (the most familiar with).
