She comes to fight in the final battle. And Ginny is jealous enough of her to make sure that she doesn't take Harry to Ravenclaw's common room. Other than that, we don't know.
Cho Chang and Ginny Weasley.
Ginny Weasley - Bonnie Wright. Ron Weasley - Rupert Grint. Cho Chang - Katie Leung. Draco Malfoy - Tom Felton. Hermione Granger - Emma Watson.
Ginny Weasley and Cho Chang are not places, so I'm guessing your asking who are Ginny and Cho. Ginny Weasley is Ron Weasley's younger sister. She is the youngest Weasley and the only girl. In the epilog of the last book/movie, she marries Harry Potter. Cho Chang first appears in the fourth movie, Harry Potter and the Goblet of Fire. She is Harry's first love interest, but is dating Cedric Diggory through out the movie/book. When Cedric is killed at the end of the fourth movie/book, Harry briefly dates her. After the fifth book/movie, she is no longer an important part of the series.

In the movies I think Hermione likes Harry then Cho Chang then Ginny.
In the book he kisses Ginny in her room before being walked in on by Ron and Hermione. In the film he kisses Ginny in the Burrow kitchen before noticing that Fred is watching them :)
First, he likes Cho Chang, then he likes Ginny Weasley(Ron's little sister), but he ends up marrying Ginny.
