bạn ơi cái này dịch trên file pdf được không ạ?

If I could give you feedback about your grammar mistake, or spelling error... I think I would be able to teach English, hehehe.
Just kidding! I know that there must be st wrong in your story, but I'm not sure that it's because of your mistake or my limited vocabulary. I'm not sure.
By the way, I think your idea of creating this topic is very interesting. This is a room for us to practice English and chatting with each other about everything in life, and from that, our English will be improved. I find difficult to learn new vocabulary, do you have any suggestion to make it easier and share with me?
