Today I want to tell everyone about that I made an introduction about why 737 Max 8 crashed, and if anyone is interested in it, please watch the video.
I think a lot of people are interested in it, so I wish you can watch my video, I introduced it in Mandarin, and if you just know English, you can look at the words.
I think the introduction I made is a very good thing, because it helps me to improve talking, and say out the thing I knew.
