China attaches great importance to the design of paper money and regards it as the face of the country without any flaws. However, we can still find that the design of China banknotes is different, that is, the handwriting is wrong. Are the two on RMB 20 yuan different from the two on RMB 20? Some "two" characters are above "one" and some are below "one". Which one should have the upper hand?
In fact, this is not a typo, but the person who wrote this number for the banknote is not caused by one person. The words on China banknotes are not printed by computer, and ordinary people can't write them. They are written by calligraphers. But for the sake of confidentiality and anti-counterfeiting, which calligrapher wrote it will not be announced to the outside world. Even calligraphers themselves don't know that when they are asked to write these numbers and words, they are used to make money. So I feel very relaxed when I write, and my calligraphy is chic, and I can't see any dullness. When several calligraphers have finished writing the specified characters, these characters will be selected by the bank, and the most satisfactory characters will be selected as the characters on the banknote, which is the source of the numbers and characters on the banknote.
The problem is that the calligraphers who participated in the screening received calligraphy training in different ways, not the unified finished products made on the assembly line, but after their own tempering, they reached a successful step. More importantly, the evolution of China characters, many of which were not like this before, took a long time from traditional Chinese characters to simplified Chinese characters. When calligraphers were trained, some accepted the reality that China characters changed from traditional characters to simplified characters, some insisted on writing traditional characters, and some insisted on writing archaic characters. The word "er" has different results in the development and change of Chinese characters. Therefore, whether the word "er" is above the word "one" or below the word "one", there is nothing wrong with the word "er". How to write depends entirely on the habits and hobbies of calligraphers.
Therefore, when choosing these "two", banks may think that these two different ways of writing are beautiful and are unwilling to give up either one, so they choose both. This is why there are two "er" s on the RMB.
