Yes, this is exactly the same as driving a car on the road: "X! Red light again!" "Oh, yellow light, hurry up~" "Green light, feel good~" - from the picture It doesn't seem to be PS, so there is only one question in the next question. Which country's intersection is actually so creative?

When a junction box is used for every electrical connection in a building it is much easier to locate and repair any electrical problems that come up.
When some connections are made without junction boxes, such as inside wall cavities or in hidden ceiling or attic locations, the likelihood future problems increases.
Every electrical connection should be inside a protective box that is easy to find and access.
