My friend Betty sent me two pictures of the Night Blooming Cereus. It's a beautiful flower.
As the name suggests, Night Blooming Cereus always blooms at night and only stays a few hours, people have to stay up waiting for it to appear at night.
In China, it's called Tan Flower. The Chinese word "Tan" is put together by two words, "Sun" and "Cloud". The name shows the beauty of the flower. When put on a light, the flower is a vivid white with a feel of transparency.

Have you ever seen the real flower before? Find one at least once in your life.
