An artist named Lin lives in a secluded spot in the mountains of Sanyi, Miaoli, where even the post office refuses to serve him. He has to pick up his mail at a general store two kilometers away. But once he discovered that the "black cats" would pick up from and deliver to his house, he became a loyal customer.
藝術工作者林先生，則深居在連郵差都不願進入的苗栗三義山區，每次有信件都要到離家二公里外的路邊雜貨店領取；自從他發現宅急便可以到家取、送件後，自然也成了忠實客戶。
