Dear Mr.Ban Ki-moon,
I am a university student in China,and I’m writing to tell you something annoying.
I’m a color blind boy,and we people with colorblindness in China are living a difficult life.
First,we’re unable to do many jobs,such as doctors,painters,some kinds of workers,etc.We all know that we color blind people can’t do jobs like piolots,but can we do jobs like doctors,chemistry teachers in high schools? As I know,in many countries,color blind people can do jobs like doctors and painters.But in China,we never have chances to do such jobs.What’s worse,though many jobs don’t require a good color vision,like radiologists and ticket sellors in train stations,we are not allowed to do them at all.Sometimes,some companies deny clerks with color blindness,even if their jobs don’t require a good color vision,and they are allowed to do the same job in other companies.
I dreamed of being a doctor when I was a little boy.But unfortunately,I will never have the chance to achieve my dream,and there are so many unlucky boys like me in China.
Another serious problem is:we can’t get a driver’s lescence.According to the law in China,we can’t drive.But as I can see,the red light and the green light is so diffirent,but the red light and the yellow light looks just alike sometimes.I think we can drive cars,and colorblindness doesn’t affict so much.A fact is that some color blind people bride the doctors and they“pass” the color vision test.There’re some color blind people driving in China,and never have they caused any accidents.As I know, color blind people can drive,and I think we shouldn’t be banned from driving in China.
I think a new kind of traffic light should be used.Apart from different color,every light has its own shape.For example,a“V”stands for a green light,a“X”stands for a red light,a“O”stands for a yellow light.In this way,everyone who can see the lights can distinguish different lights.

我最终还是寄出去了，也许石沉大海，也许有了回应，世人知道了我的秘密，我身败名裂，被迫。。也许从此。。。。但是，毕竟我还有梦想，我不甘心，我相信未来。

截至目前，没有收到任何回复。但是，只要我还抱着改变世界，实现梦想的决心，我就不会放弃。
其实我们就是处于劣势，因为这个世界不是我们主导的，我们和正常人真的不一样。所以一方面我们要努力争取，另一方面，要努力和正常人一起寻找治疗色觉异常的方法。
我前两天给美国在这方面做研究的科学家发了邮件，表示支持他们的工作，愿意参加临床实验，至今没有回音。
似乎现在比从前更加艰难了，但是也许我们离成功更近了。

哭吧，眼泪流干了，也就不会哭了
