Ecologically friendly wooden toys like whistles, horses, tiny furniture, jumping horses, spinning dancers, and flapping birds that operate on indigenous, age-old mechanical engineering techniques are both a fascinating experience and an eye-opener to the depth and breadth of Chinese traditional handicraft knowledge and practices. They symbolize the rich and varied cultural heritage of China. These toys are finely hand-crafted from soft wood and are highlighted with imaginary colorful paintings, representative of unique Chinese painting traditions.
