Sorry. 

Ahh, I'm so sorry about add the same article on Cho Chang like She must have been second year in Harry Potter and the Philospoher's Stone. In the Magazine 2005 July, the time when Harry Potter and the Half Blood Prince book was published by J.K Rowling, J.K Rowling already said that ''I'm not going to write about her since graduated from Hogwart." from an interview. That means She is probably not going to appear in Book Seven. So, May I just leave like this?
