    “Chunyan worked hard on this project, but was unable to complete it because of basic lack of understanding of things like HTML and CSS. She got upset when I wanted her to complete the project and pointed out quality problems with the delivery. Several times along the way she wanted to deliver the unfinished project and tried to convince me that I didn't need the requirements I had described. As my goal is to actually get the result and she seems unable to do that, it was best for me to close the project. We reached a compromise where I paid her partially and I had to promise her to give her 5 stars in order for us to avoid a time consuming conflict. So here it is, but it is not really a 5-star project. So any of the other 5 star ratings she got should also be questioned in my opinion.”
