At the beginning, let's first take a few yu ziping color blindness detection charts

Picture above, if your answer isn't quite right, then congratulations. You are most likely to be labeled as colorblind or color-deficient by your tester. The use of color blindness, a test method of killing with a pole, is very common in China. It has brought great trouble to the lives and employment of many people. What is even more hateful is that it has become the code of wealth for some people.
I am in a small town in Wenzhou, and some time ago my mother asked an instructor to take me to the vehicle management office to register for a driver's license. During the physical examination, the inspector randomly asked for a few pictures, and there were two of them that I could not identify all the numbers. He shook his head helplessly, "How are you colorblind?" You can't pass a medical exam. I said, "I can tell the color, how can it be color blindness." He then handed me an address and asked me to go to the designated local hospital for testing. The next day the coach took me to the designated hospital for a physical examination. The same plot was staged, and the doctor did not let me pass because I answered a picture incorrectly. I explained to him bitterly that some of me could see it, and some of it was really not visible, but I was not colorblind. After coming out, he got into the car with the coach, and he seemed to have expected it: "Didn't pass?" I know a scalper, only need 1200, can help you get things done? "I'm full of question marks, what is it?" Is this human sophistication? Greetings from the heart directly. I need 1200 for a person who can distinguish colors to open a color weakness certificate?
Unexpectedly, the coach's later statement was even more outrageous, he said: "You quickly hand over the money, otherwise the designated hospital input system is weak, then you will not be able to take the driver's license for a lifetime." "I didn't say anything until I got home.
It is also sad to think about it, the residents of our town are generally not highly educated, and this kind of inferior scam must have been set by many people.
In fact, the full name of the color blindness detection map is Ishihara's color blindness detection map. It was published in 1917 by Professor Shinobu Ishihara of the University of Tokyo. Then brought into China by Yu Ziping in 1958, all the color vision check charts used in our country so far are not much different from those, but the graphics have changed and the number of pages has increased. In Japan and Europe and the United States, for nearly 80 years in the early years, these countries also used "color vision detection map" as a tool to detect color vision. With the development of the times and a large number of practices, these countries have found that the color blindness detection map drawing method adopts the ability to steal the color discrimination ability of the subject into the perception of color brightness. Since there is no causal relationship between these two concepts. In this case, the test results of this color blindness examination map can not confirm the color discrimination ability of the subject at all, and the test results are obviously wrong. This test was abolished in the 1990s.
At the Fourth Session of the Eleventh People's Congress in 2011. Due to the bias and misunderstanding of the problem of abnormal color vision, coupled with the fact that the old original regulations have not been re-examined in today's highly developed science and technology, the current relevant policies have many restrictions on the choice of color vision majors in China, employment, joining the army, applying for a driver's license, etc., so that they have been treated unfairly. "Wang Chunlan, deputy to the National People's Congress and chief physician of the Department of Plastic Surgery of the First Affiliated Hospital of Anhui Medical University, suggested that the relevant departments seriously study and lift the restrictions on the rights of people with abnormal color vision."
However, as of today, the proposal has not been accepted for implementation. The birthplace of the color vision checkmap was also abolished early. In our country, this open-book examination has not been able to reach a passing score for a long time.
