As the leader, Shanghai Bicycle Factory, which produces permanent brands, ranks first in terms of output, quality, variety, popularity and long history. 1949 in the early days of Shanghai's liberation, the "wrench" brand was produced by Shanghai Automobile Factory of East China Ministry of Industry, symbolizing the characteristics of the working class being the masters of the country. At that time, the use of homonyms in trademarks was popular, with white bears and the earth as patterns and the homonyms of "bear balls" as "permanent" cards. Because the white bear and the earth feel heavy, there is no light pleasure, so the design was quickly cancelled and the word "permanent" was added to the emblem of the Ministry of Industry (from 195 1 New Year's Day) to 1956. After that, the "permanent" bicycle factory entrusted Shanghai Art Design Company to carry out logo design business.

1955, the first engine department put forward the design of standard special-shaped bicycle (referred to as "calibration bike"). At the end of the same year, Shanghai Bicycle Factory took the lead in successfully trial-producing the 28-inch PA-1"Calibration Car", which reflected the starting point of the overall transition of bicycle specifications in China from English to metric. At that time, the permanent factory held a comparative exhibition of new and old products and parts. Many workers asked whether it was possible to design a permanent new trademark comparable to that of a permanent bicycle, and to break away from the linear artistic word frame such as "permanent" used at the beginning of liberation. With the birth of 1 1 "calibration car", a permanent new trademark will soon come out.

At that time, there was no full-time designer in Shanghai Bicycle Factory. Shao Zaisheng, an employee of the planning department, loved art when he was born, so the factory department transferred him to design work. After the successful trial production of the calibration car, he once conceived and designed many permanent trademark patterns, but they were not ideal. The factory leaders supported him to learn from the experts of Shanghai Art Design Company. At that time, experts also designed many schemes, which were not ideal. Experts also backed out and designed them to the point of "no water".

By chance, Shao Zaisheng saw a font design pattern in a Japanese magazine, which was to skillfully combine fonts into interesting shapes. Inspired by this, Shao Zaisheng conceived a design idea based on bicycle composition and introduced it to Mr. Zhang Xuefu of Shanghai Art Design Company. Together, they repeatedly scrutinized many compositions and finally completed a permanent trademark with bicycle images as the composition. Because there are only two permanent Chinese characters that can be interpreted as bicycle shapes, they can't be made into logo marks, and there is no decoration, so Mr. Ni Changming, deputy director of the decoration design office of Shanghai Art Design Company, designed logo marks (1957): gears above, rice ears below, representing workers, farmers and the public respectively; There is a flashing five-star in the middle, and the words "car shape is permanent" are embedded in the middle. The place name below is Shanghai. This design actually follows the conception and composition of the national emblem.

In the future, because the logo is too similar to the national emblem, it is not suitable for being used as a symbol of goods. Therefore, in 1976, I designed a trademark license plate that reflects the new era of reform and opening up, instead of the national emblem style symbol. Because the original user brand of the national emblem style logo is deeply impressed, the new logo style is quite different from the old logo style, which has certain influence on the brand image extension. So the factory considered absorbing the striking features of the original national emblem style with white characters on the red background and redesigned it, so I designed a modern permanent trademark logo (1980) on the basis of traditional culture, which has been in use ever since.
