Pot Luck Party III

In the middle of the party, teachers arranged a game for us. All the students of PH1 and PH2 in one group while one more group is from PH3 and PH4.
How do play the game? Actually it was simple. We needed to grab a chair to sit once the music is stopped. I was quite expert on this game. I managed to grab the chair. I get the fourth place in this game. I really enjoyed the game and it was excited.
