According to old Brazil hand Chien Han- sheng, head of the Taipei City chapter of the Kuomintang, Taiwanese traveling salesmen were diligent and good at doing business, often promoting sales through popular easy-payment schemes, whereby the first installment often covered their costs and the rest was pure profit; and settling the next monthly bill gave an opportunity to bring around new wares to hawk.
旅居巴西多年的國民黨台北市黨部主委簡漢生也指出，台灣客勤快又會做生意，常以「分期付款」方式促銷，極易打動客戶，而且往往光是「頭款」就已經夠本，其他的都是淨賺；再來藉著下個月去收帳時，又可以順理成章地帶些新貨去兜售。
