About the project of obelisk, my work is different with most of students. My work is to find a good place for every obelisk. The purpose of this work is try to make more people to see the obelisk, and if somebody stand beside one obelisk, he/she will easy to find another one. For this purpose, the obelisks should be put at the place where is easy to see by people, like cross, flat area. And the target area is a wide area. We get 32 places in total. We mark them from NO 1 to NO 32. We use chopsticks to made signs at first. But we found chopstick is easy to get hurt and missing. At last, we use iron instead of chopsticks, iron stick and iron slice. And we take photoes for every place. The map could show us the 32 places clearly.
