Let China go out better

When I am not at work, I enjoy spending time with my family. I am lucky to have a beautiful wife and two wonderful children, Jennifer and Michael. I love family dinners, various outings, and sports activities but I also have one favorite hobby. Despite the fact that it is not quite a men’s one, I am passionate about cooking. The cooking process takes my daily stress away and inspires me to create new tastes and recipes and share them with others. Every weekend I pamper my family with something special.
