The weather in Beijing

Now the most prevalent word in China is the haze. I want to share a joke happened in this morning -- that was when i took a taxi in this morning, I was confused when the driver told said to me that "Good morning, and you should choose a red or a green or a yellow clothes to capture my attention", and then he explained to me "only the colour of the traffic light is distinct, your khaki clothes made u dissolved in the haze".
Yeah, it is a joke but it cannot make anyone simle smile.

Hello, I am not a native English speaker but I hope my correction helps.

Your note is OK except for some spelling mistakes. Here are some suggestions:

You mentioned the joke happened in the morning, so you don't need to mention it again in your joke.

"choose a red or a green or a yellow clothes" can be expressed more concisely: "choose a clothes in red, green or yellow".

I think "say to me" is better than "tell me" in the situation where you are telling a story and quoting his words directly.

Finally, is there still haze in Beijing now? I thought this story is more likely to happen in Shanghai days ago:)
