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!
