frist : we buy a pine tree first.

　　and then: we erect it.

　　secondly: we hang with the neon on the pine tree.

　　and then: we hang with a few small ornaments products on the tree.

　　again then: we readjust oneself to a certain extent with the star in the pine tree top.

　　at last: we readjust oneself to a certain extent low with the gift in the pine tree.

　　such has made a christmas tree right away , schoolmates have also tried!
