Everyone who knows Mr. Zheng will be attracted by his hearty laughter, touched by his enthusiastic recommendation, and will be convinced by his vitality. As soon as I talked about the picture book and the children's picture, Mr. Zheng's words opened up. He wouldn't wait to share his findings and feelings, and then extend and associate various creative ideas.

This " The power of children's painting---- The grandfather of the picture book leads you to see children's pictures and understand Taiwan." has Mr. Zheng's love and dedication to children's paintings. He also has a love for children and aspirations for children's art education. The paintings in it are spent on teacher Zheng for half a century. The collection also records the brilliant achievements of Zheng’s work in children’s art education.

Teacher Zheng is eighty years old, but he is always energetic to do things, and he puts all his thoughts into it. Just like a child, even a young man of 20 years old sees himself. !

I hope that everyone can read this book and return to the happy and worry-free time of childhood. They can regain the joy of playing with the brush and experience the beauty and infinite charm of the creation together with the children.
