Q: Preferable short poems or phrases in Chinese.
this one is about cranes We thought they were gulls at first, while they were distant- The two cranes flying out of a natural morning, They circled twice about our house and sank, Their long legs drooping, down over the wood. We saw their wings flash white, Frayed at the black tip, And heard their harsh cry, like a rusty screw.

Q: My hubby just passed his crane test yesterday, and I was wondering how much they pay? He was told to ask for 50k a year..that includes crane time where he works. Can we really ask that? He sets trusses for a big lumber company in Missoula Mt. Any help would be great.
Huh, I thought crane ops got paid by the tonnage they lift. Maybe there is a base pay in addition to it. But to answer your question, I don't know.
Q: my HSAP prep teacher wants us to find instructions on how to make an oragami crane.She said that it has to be less than 24 steps.I have looked on the internet and I cannot find anything.I need this by tomorrow.Please help!
Start with a square piece of paper. You got that? Fold the paper corner to corner to get a large right triangle, and fold it corner to corner again to get a smaller triangle. You got that ,or did I lose you. Open the paper, and you will see a big X. Never mind the X. We will come back to it. Now fold the paper side to side to get a rectangle, and fold the two SHORT SIDES to the X fold. Open and do the other two by repeating what you just did. Open the paper FLAT. You can now see a 4 pointed star. Along the four sides of the square, push down on the perimeter of the star to make the star come up. Fold down until you have a flat KITE. Make sure you have 2 flaps on each side. What you are looking at now is one wing, and the other one is in the back. The neck and head are inside the wings. Pull them out half way to expose them. Fold one side at the tip to make a head. If you did everything correctly, and hold under the neck with one hand and pull the tail with the other hand, the crane should flap its wing. Write back if you need more help.
Q: You know those big cranes that sometimes hang above constructed buildings. I usually thought a crane is used to build that crane but then how is that first crane that built the crane get there in the first place?
The first crane generally arrives on a trailer or on it's own wheels.
