Because the maximum number of dice is 6.

If you don't vote for 6, the highest score can only be 5+5+5= 15.

Because Faye Wong/KLOC scored-0/6, he scored 6 points at least once.

Wrong smile:

Zhang Ming * * * got 12.

Throw six points at a time, and there are six points left.

These six points can have many combinations, such as 1 and 5, 2 and 4, quadratic 3, etc.

So it is possible for Zhang Ming to score 6 points at a time.
