The use of minority languages on RMB not only reflects that China is a multi-ethnic country with great unity of all ethnic groups, but also reflects the development and evolution of minority languages in China, which can be said to be one of the main characteristics of RMB.
In the past, there were no Braille symbols in the currencies of all countries in the world, and the blind mainly distinguished different denominations by increasing the face width from small to large. Metal coins can be identified by gradually increasing the diameter of money, or using different materials to make blind people feel the size and weight, or changing the shapes of coins with different denominations (such as circle, square, diamond, polygon, ripple, etc.). ) and increase the thickness so that the blind can correctly identify these coins with different denominations. However, coins in contemporary countries around the world began to pay attention to the use of Braille symbols, which is convenient for the blind. Relatively speaking, it is rare to print Braille symbols on banknotes all over the world at present. The third set of RMB banknotes in China was not printed in Braille. When designing and printing the fourth set of RMB, the Central Committee of China and the State Council instructed the People's Bank of China to print more Braille symbols on major currencies for the convenience of the blind. Therefore, 1 yuan, 2 yuan, 5 yuan and 10 yuan coupons are printed with 1, 2 (vertical column), 2 (diagonal column) and 4 small black dots in the lower left corner of the front; 50 yuan and 100 yuan coupons are printed with 5 and 7 small black dots in the lower right corner of the front respectively. These little black dots are arranged in a complicated way. If you touch them carefully, you can feel a slight bulge. Blind people can identify the face value by touching the number and distribution of black spots. There are millions of blind people in China. They are a special consumer group and should be concerned by the society. Braille symbols are printed on RMB, which shows the concern of the party and government for these blind people.
