Study Break Starts~~~

Hmmmm..... should i be happy because study break starts? DEFINITELY NO !!!! Coz i wont be able to enquire my lecturers when i got questions !!!! but stil got email and their hp no. XD. Although its a break, i have to study for my exams (20th and 22nd May + 3rd and 5th June) ~~~ so is it enjoy or suffer?

Today's class was quite relaxing though.... Before Mr. Sam started discussing questions, he tortured my class with a quiz (true story during the ancient China, forgot which dynasty le). For those who wants to torture themselves please read the quiz below. Then, for Mr. Awang's class... he is quite considerate~~for letting us skip his class because he knows that we are having mocks and exams. This is what he said : "I will be in the class for this week, if anyone don't feel like coming because u need to study for ur exams, go ahead and don't worry about your attendance. I will still put you SPIRITUALLY present ." Since this semester there is no exam for accounts.

Then afternoon, i continue in my Japanese Language Class.. I dunno should i consider myself good or bad =x. Cause today only one person turned up- Phui Yi (the top student of my senior batch). So today's class is a 1 to 1 class. As i said, she is top student, she can absorb things quickly.... So i found it very very very very easy to teach her Japanese XD. But too bad she cant continue to learn Jap with me because she have to go back Johor after this sem~~~ T~T....

So this is how the quiz go~~~ During the ancient times in China, 4 refugees escaped from their country to a desert in China. So there were armies chasing them, they ran to a watchtower in the desert and begged the chief to let them hide on top of the watchtower. as shown below. This watchtower is very unique that from north, south, east and west, you can always see 7 people only. The chief of the watchtower agreed to hide them. When the armies arrived, they still see 7 people from the 4 directions. How did the 4 refugees manage to escape from the armies?
This is the plan showing the number of guards standing on the watchtower, including the chief before the refugees arrived.
Reminder: no guards left the watchtower, the refugees wore the extra guard suits and u can always see 7 people from the 4 directions.
Hint: Its a maths and real life question. Please don't say its impossible.
