问题
Today when I was working with Git I got something wrong and I really cannot understand it. Our team has a private github repo and I pulled some changes from that shared repo. After I did the pull, I can see every changes and the details in git log and everything is all correct. Problem is if you open the file, the changes are not there. I trust git, I'm thinking myself or my teammate did something wrong but for right now I really have no idea how this could happen. If you have any similar experience, suggestions, guess of the reason or deductions, please leave a comment. Thank you guys.
