The other night I was at a conference which had organized a 抽奖 (prize drawing) activity.  I bought 9 tickets at the time, trying to improve my chances of winning.  Win I did.  There were KTV (karaoke) passes and 餐卷 (food coupons), which could be used another night.  Given that the tickets were 10USD or 100RMB, I went with the 10USD tickets, saving between 30-40RMB per ticket just by paying in US bills- very 划算 (good deal).  The highlight of the night was when I won a 空气净化器 (air purifier) valued at over 1500USD!  I ran up to the stage while 狂笑 (laughing crazily) and was very 得意洋洋 (smug) at a 夜总会 (nightclub) following the event.  The only drawback is that my 嗓子 (throat) is still rather 哑 (scratchy) from all the yelling.
