What is the perfect floral arrangement of orchids?

Orchids have three skills: 1. Floriculture-patterns and colors of flowers; 2. Ye Yi-line art, point art, crystal art and so on; 3. Formal art-the shape of leaves, such as dwarf species and exotic leaves (Wenshan Jialong). Orchids with more than 1+2/3 are perfect in floral art. Of course, Sanyi is top-notch. For example, the short-term art of lotus petals is Sanyilan.
