Good morning, everyone!

I’m Li Hua from Xingguang Middle School. The topic of my speech is “My Chinese Dream”.

As we know, the education of rural areas is falling behind other areas. And the children there are longing for knowledge. Therefore, the problem about the lack of teachers is especially serious. It puzzles me that parents and friends aren’t in favour of my idea of being a rural teacher. And they think I am foolish. I understand their thoughts and feelings, but I think the children in rural areas are in great need of me. I will study hared to go college, thus realizing my dream.

I won’t regret my choice. I will struggle for my dream. e on and join me! Thank You!
