The creation of the majority of Hong Kong signs falls into four patterns:
1. Simulation - Signs that simulate the appearance of things, such as "Aircraft", "Boat"
2. Mimicry - Signs that imitate the movement or action of doing something, such as "Take a picture", "Eat "
3. Iconicity - Signs that borrow the shapes of Chinese characters, such as "People", "Workers", "King"
4. Metaphor - Signs that represent ideas or concepts, for example, "Learning", "Forget"
