I have one role called Content Editor and 2 users Chang and Liang with the same role. They both can add/edit their own content. The role permission is set in such a way that they can only edit own content. But however when Chang goes to http://Drupalsite/admin/content he can see all the contents written by all the users.

How to restrict Chang to see only the contents he have written in http://Drupalsite/admin/content link?

I have a role called Content Editor and 2 users Chang and Liang with that same role. 

They can both add/edit their own content. The role permission is set in such a way that they can only edit own content.

However, when Chang navigates to /admin/content, this user can see all the contents written by all the users.

How to restrict Chang so that he can see only the contents he has written when visiting the /admin/content link?
