Opening ceremony of Pyeongchang winter olympics.

Yesterday night, opening ceremony of pyeongchang winter olympics was held. 🌏

Because actually I'm not interested in international sports events like Olympics, Worldcup, so in this time, pyeongchang winter olympics was not my matter of interest, either.

But after hearing opening ceremony was awesome, I got interested more and more.
Eventually I found and saw the video of opening ceremony, It was impressive as I heard. 👍

You can see the video below.

Have you watched this video? Then, what do you think about the things that make olympics rings? Computer graphics??

No...

"They are 1,218 drones."

It is said that 1,218 drones renew guinness world record as the largest drones flying at the same time and they are controlled by just a computer and a person. Isn't it splendid??😎
