For Pan personally, searching for and photographing frogs is a test of his physical and mental endurance. For the frogs, there is now a photographic record of 31 species of frogs at all stages of life: birth, maturation, and reproduction. This is the first comprehensive picture of frog life in Taiwan available to the outside world.
對他自己，尋找、拍攝青蛙是體力與耐力的挑戰；對青蛙，他記錄、拍攝三十一種青蛙從蝌蚪、成蛙、再到繁殖孵化的過程，是台灣青蛙生活第一次被完整公諸於世。
