If you get the right weather conditions, and position yourself in the same spot, you can see this 'test launch' several times a week.
I've seen the same thing and I live in the middle of the U.S. Those Chinese missiles have a really impressive thrust time and awesome range. Wish we had some.
Me too. I live on the east side of Lake Michigan, pretty close to being under a commercial jet route. Around sunset I can see "launches" almost every day...providing it's not cloudy.
