In the picture, we can see five fingers of a hand, in which of them there are notes.

It reads from the thumb that I am powerful. It reads form the index finger that it is the most flexible for me to grab things. It reads from the middle finger that I am the tallest. It reads from the ring finger that the whole hand is disabled without me. It reads from the little finger that I am good at pick one's ear.

This image shows that five fingers carry out their own duties. Not a single one can be omitted.

And therefore, I hold a firm belief that union is the basis of achievement.
