When he was investigating Yuching in 1985, Lin took a stroll through the countryside. There he witnessed the residents performing a Daoist religious ceremony. When the ceremony was over, the pork from the sacrificed pig was equally divided among the residents and the leftover pig's head was just tossed away at the foot of a mango tree. The smelly pigs head attracted a large swarm of blowflies.
1985 年，他在玉井鄉調查時，有一回在鄉間閒逛，附近居民正在酬神做醮，儀式結束後，居民平分拜神的豬肉，剩下的豬頭則被隨手丟棄在一棵土芒果樹下，發臭的豬頭引來大群「麗蠅」。
