Patrick Lau, one of my friend I proud of. He wrote a book about e-commerce and he invite me and Mr. Ivan Wang to design a cover for his book. Patrick, he did 3 cover design by himself when I and Ivan both created one. Finally we have 5 cover design for publisher to choose. Although the publisher chose Patrick's cover design finally, we are still happy to do so. At least, I have a chance to work with him again, a great lesson!
