A woman wearing a veil and holding a cage with a bird in it is walking past a wall with a bird painted on it and a red line painted on the wall and above the bird. The bird on the wall, the red line, and the cage in the woman's hand are both associations of prohibition and captivity, and in addition to the woman's clothing, which is the hijab, it is absolutely mandatory for women to wear it due to the hijab law in Iran.
