At the end of the interview, Cheng's eldest daughter-in-law pulls out a video made by the National Chengchih University's China Border Area Research Institute ten years ago and complains, "None of his sons and grandsons are picking up his work. If you hadn't come to interview him, he wouldn't even want to talk about it. Perhaps the spirit of puma will leave with him."
採訪結束，程牛屎的長媳拿出一卷十年前政治大學邊政研究所製作的布馬錄影帶，惋惜地說「這子孫沒人接，要不是你們來採訪，他也不太愛說，布馬的全精神就恐怕要隨他去了。」
