Science and Mathematics Week

[[IT room]]
Just now I went to the hall to visit the " Science and Mathematics Week".
I took part in "Sudoku Comepetition". But I just simply played it, fill in the blanks without think of it.
My senior, Jun Jie sir was keeping laughing me... Because I simply fill in the blanks.
So, he taught me how to play the sudoku=.=ll
Later, I challenged him>.<
[[I LOSE IT]~~
“认真想想，别让你的脑遭蹋。”
I really appreciate you for teaching me...
"Jun Jie sir, you really is a good senior, not only teaching me on scout knowldge,even maths"
