Changsha Evening News (Reporter Bu Jinwen) Yesterday, Grandma Liu, who lives in Mawangdui, sold a sewing machine from over 30 years ago to a waste collector for 20 yuan, while Grandma Liu's grandson Xiao Wang successfully sold the sewing machine manual online for more than 20 yuan. The reporter learned that at present, these product manuals, which have been popular for some years, have become an alternative collection for many people, with prices ranging from a few yuan to over a hundred yuan.

The old manual is more attractive than the actual product

　
According to Grandma Liu, her pedal sewing machine was produced in the 1970s, which is large and very old and bulky, and many waste collectors are unwilling to take it. Grandma Liu spoke well and finally sold it to a vendor for 20 yuan. To Grandma Liu's surprise, a user manual accompanying it was sold online by her grandson Xiao Wang for 30 yuan. Xiao Wang told reporters that at that time, he hung photos of the product manual online with a try mentality. Unexpectedly, someone booked it the next day, and there were still many people who wanted to buy it. This manual, printed in the 1970s, is only palm sized and consists of 58 pages. It provides a detailed introduction to various accessories, usage, and maintenance methods of the sewing machine. The content is detailed to the point of introducing the function of a small wrench on a whole page, and the cover of the manual also features a paragraph of "Chairman Mao's quotation", which is still bright and red in color.

 　
37 years ago, the manual sold for 850 yuan

The reporter searched for "instructions" in the "antique collection" category of goods on Taobao. com and found 2419 relevant records. The product instructions sold separately are mainly divided into two categories: one is the instructions for rare goods on the market today; Another type is the old manual. The age span of the old manual ranges from the Republic of China period to the early 1990s, covering dozens of types such as electrical appliances, instruments, pharmaceuticals, daily necessities, and literary and artistic products. Most of their manufacturers no longer exist, and their products have long ceased production. Among them, alternative products or manuals with era characteristics are the most popular, with rare tape manuals and precision instrument manuals priced above 50 yuan. The reporter saw on a second-hand auction website that a set of 37 years ago "precision instrument manuals with quotes" was sold for 850 yuan.
