The charcoal for heating the boat...

Before you read this, try to read this story first.

At that night, I thought about my coming 20th birthaday, I thought until 2.50 a.m. After that, I began to study for tomorrow PBL until 4 am. This is because I didn't forget the PBL also contributes 5% to our continuous assessment.

Therefore, after I thought for a long time, I think my lucky number for today is

2 7 . 8 0

And I have decided to buy 4-D from the captain of the boat, so that I have a chance to win the Grand Prize and no need to study...

Haha... LOL...
