"description": "Hello everybody,time flies.A few days latervthe AGA Tournament closing ceremony is coming soon. This tournament proves us a communication from country to country.And It makes us learn how players move and do reflections.I think it is the best way to prove linking from country to country. There are many tournaments in it.Such as 9x9,Blitz or open.Their are many choices to choose .The tournament was not face to face.However,it was an experience to play,review and enjoy! Sadly,even good things also have an ending.We have a few days to end the tournament.Therefore,I held a Closing tournament which made all participants cherish the moment of playing with other participants. What I believe is, although the tournament is over.We’ll still keep staying at the AGA group. This is the end of my speech.Thank you! Speaker sko0",
