typical chinese coder.........sorry...

sorry to hear this, but remember, next time $hit happens,
1. quickly admit it's your fault.
2. spend more time blaming the system.

if this is a such important delivable, how the hell the QA told u the problem one day(or to be precise, FEW HOURS before the prod rlease??)
remeber brother, human is allowed to make mistake, you are victim too. if the QA process was impl. correctly, you wouldn't be cornered like this.

don't try to be a $hit baskit. i would have a BIG fight with the QA if i was u, and i would blame QA for this damage.

good luck.
