Mingli...

Yesterday when I was slacking at the backstage with Renjie,Mingli came up to me to tell me that I already know that I helped in QiHang.
He said that the SNG girls was telling him about how my props works and what happened to them.They also said that they were laughing while they tell Mingli about it.Now a question to me,are they laughing at my props or what happened during QiHang was so funny.
Mingli moreover "suan" me to say that I no standard.
Why can't he just say "good try" or more encouraging words?Why must he always "suan" me?Same as to the drama camp 2003.
