Like a child who never grew up, Chang still takes great pleasure in the "wisdom of toys," but beyond this he is also devoted to finding new life for traditional Chinese toys, so that children everywhere can share in the enjoyment of them.
他﹘﹘張世宗，一個童心未泯的大男人，悠游在中國童玩的世界，與「玩具的智慧」鬥智始終不改其樂。獨樂樂之外，他更致力要讓傳統童玩活出新生命，讓眾家小朋友一起樂樂。
