1. Prepare a RMB bill, put it on the table, face up, gently fold the right side to the middle, and then press the red number "100" with your nails to fold the edge of the pattern in half.

2. After folding, there will be two triangles on the reverse side, which are aligned, folded upwards from the middle, and then the wings on both sides are buckled downwards to make them look like cowherd and weaver girl from the air.

3. Bend the longitudinal broken line in the center of the butterfly wing with a nail or a pen tip, and then bend the outer side of the wing inward to make the wing fit better.

4. The butterfly wings are reversed, and the picture is in the shape of "iron fist invincible flowers without shadow", and then the curved objects on both sides are bent to complete the whole butterfly making process.

These are the simple steps of folding butterflies in RMB. It should be noted that you should keep your fingers flexible in the process of making, and don't use too much force to avoid damaging the banknotes.

As follows:

Butterfly is the collective name of Insecta, Diptera, Lepidoptera and Butterfly Subclass, with nearly 20,000 recorded species in the world. China is rich in butterfly resources, with more than 2,000 recorded species.

The tentacles of most butterflies are rod-shaped or hammer-shaped, slender and slightly thick at the bottom. During the day, the wing interlocking device is a wing hug, and the body is slender. Butterflies are called "flying flowers" and are very beautiful insects.

Most butterflies are medium and large, with wings spread between 15~260 mm and two pairs of membranous wings. The body is long and cylindrical, and it is divided into three parts: head, chest and abdomen. The body and wing membrane are covered with scales and hair, forming stripes of various colors.

Like all animals, butterfly classification takes "species" as the basic unit. Butterflies of the same species must be similar in appearance, have the same blood relationship and similar living habits, and can mate with each other to produce normal offspring.

As early as 1735, the Swedish naturalist Linnaeus (1707- 1778) studied the classification of butterflies. He classified all kinds of butterflies into one genus and called them Papilio.
