"Famous people, famous words" is an educational series from 1996, presenting a number of famous persons, both Chinese and foreign, and their famous utterances. This quote from Thomas Alva Edison reads: "My philosophy of life is work. I want to reveal the mysteries of nature and serve mankind accordingly. In our short life, I don’t know what could be better than this kind of service" (我的人生哲学是工作，我要揭示大自然的奥秘，并以此为人类服务。我们在世的短暂的一生中，我不知道还有什么比这种服务更好的了).
