Villa, the reward of half life effort, is full of our beautiful yearning for the future life, not just a simple habitat. How can we depict and redefine the "space mission" in the design? Home should never be cold, no matter where you are from through the ages. The new work of Li & Du, the new "Happy Valley" built by Yueshan Lake in Guiyang, combines the good wishes of the next generation with the imagination of childhood, creating a bright and lively "Happy Valley" to meet children's all imagination. No matter how big the house is and how expensive the furniture is, there is not much for children. Why are many young people become so cold now? Because they didn't feel warmth of growing up. Family watch TV around the super big screen without spiritual dialogue. What warm memories could create in such an environment and childhood? If we don't live a warm life, how can we guide them with education of love? It takes 80 kilojoules to heat a glass of water from 0℃ to 100℃, so what if it is to warm a heart? Those bright pursuits, passion for life, benevolence in our bones, and the energy of fearless of cold wind will keep the temperature of our hearts and keep us alive. It's an opportunity for parents to recall their childhood when they grow up with their children. Living together and accompanied everywhere, but the living habits, hobbies and independent personality of each other can be completely preserved. This is what a good life should be like. It's also about the inheritance of emotion and love.
