The moral of paper cranes:

Paper cranes represent the wishes of the people who are sent. Every paper crane carries a small wish, which eventually becomes a wish. The meaning of 999 paper crane is almost the same as that of 999 roses, and they all hope that love will last forever. People who fold/kloc-0.000 paper cranes can make a wish.

In the eyes of China people, paper cranes are regarded as the patron saint of love. Carrying a paper crane is even more important than your own life. It means unrequited love for life, if you don't marry, if you don't marry.

The blue paper crane represents melancholy and broadness, with a sea of mind and lofty sentiments. Blue is usually the favorite color of poetic writers. For China people, the red paper crane is a symbol of good luck.
