Before the 1990s, China was known as the “Bicycle Kingdom.” As the leader, it is the Shanghai Bicycle Factory that produces the permanent brand and ranks first in output, quality, variety, popularity and history. In May 1949, in the early days of Shanghai's liberation, the Shanghai Car Factory of the East China Ministry of Industry produced the "Wrench" brand, symbolizing the characteristics of the working class being the masters of the country. At that time, it was more popular to use homophonic trademarks in trademarks. The white bear and the earth were used as the pattern, and the "permanent" brand was based on the homophonic pronunciation of "bear ball". Because the white bear and the earth felt heavy and not light, the pattern was quickly cancelled, and the word "permanent" was added to the emblem of the Ministry of Industry (from New Year's Day, 1951) and was used until 1956. Later, the "Forever" bicycle factory commissioned Shanghai Art Design Company to conduct logo design business.

In 1955, the First Ministry of Machinery proposed the design of standard bicycles (referred to as "calibration bicycles"). At the end of that year, Shanghai Bicycle Factory took the lead in successfully trial-producing the 28-inch PA-11 "calibration bike", which reflected the starting point for the comprehensive transition of my country's bicycle specifications from the imperial system to the metric system. At that time, the permanent factory held a comparison exhibition of new and old product parts. Many employees asked whether they could design a permanent new trademark comparable to that of Forever Bicycle, breaking away from the "forever" and other linear art word frames used in the early days of liberation. With the birth of the Type 11 "calibration car", a permanent new trademark is about to emerge.

At that time, the Shanghai Bicycle Factory did not have full-time designers. There was an employee in the planning department, Shao Zaisheng, who loved art, so the factory department assigned him to design. After the successful trial production of the calibration car, he conceived and designed many permanent trademark patterns, but none of them were ideal. The factory leaders supported him to learn from the experts of Shanghai Art Design Company. At that time, experts also designed many plans, but none of them were ideal. The experts also gave up, and the design reached the point of "endless".

By chance, Shao Zaishan saw a font design pattern in a Japanese magazine, which cleverly combined fonts into interesting shapes. Shao Zaishan was inspired by this and imagined a composition based on a bicycle. The design ideas were introduced to Mr. Zhang Xuefu of Shanghai Art Design Company. The two repeatedly deliberated on many compositions, and finally a permanent trademark with a bicycle pictogram as the composition was completed. Since there are only two Chinese characters for "forever" in the shape of a bicycle, it cannot be made into a vehicle logo and it is not decorative. Therefore, Mr. Ni Changming, deputy director of the Decoration Design Office of Shanghai Art Design Company, designed the vehicle logo (1957): Above The gears, with rice ears at the bottom, represent the workers and peasants respectively; the shining five stars are in the middle, the word "forever" in the shape of a car is inlaid in the middle, and the place name Shanghai is below. This design actually follows the conceptual composition of the national emblem.

Later, because the car logo was too similar to the national emblem, it was not suitable as a product label, so in 1976 I designed a trademark license plate that reflected the style of the new era of reform and opening up to replace the national emblem style label. Since the original user brand of the national emblem style signage is more impressive, the new signage style is quite different from the old signage style, which will have a certain impact on the brand image extension. Therefore, the factory considered absorbing the eye-catching features of the original national emblem style with red background and white characters. After redesigning the design, I designed a permanent trademark sign (1980) with a modern feel based on traditional culture, which is still in use today.
