Which way is the east? Left or right?

On the map without beacon and latitude and longitude, the east is on the right.

The universe is an infinite container. Although the universe is directional, there is no directional noun. Directional nouns on the earth are actually created by human beings subjectively and purposefully. So that human beings can identify and recognize the direction. It is a habit recognized by emperors, generals and ordinary people.

"Up north, down south, left west, right east" only applies to maps without marks and latitude and longitude nets. This is called general discrimination.

Extended data

The directions commonly used by people are mainly up, down, east, west, south and north. On the earth, the direction pointing to the center of the earth is down, the direction facing the center of the earth is up, and the up and down are vertical. What we're going to talk about next is the direction on the ground plane. On the ground plane, east (due east), west (due west), south (due south) and north (due north) are the four basic directions.

The determination of the direction on the earth is related to the rotation of the earth. From north to south, people call the direction of the earth's rotation from west to east. On the earth, the direction along the earth's rotation is east, the direction against the earth's rotation is west, and the horizon direction perpendicular to the east-west direction is called north-south direction.

The direction of the horizon is determined by latitude and longitude. Specifically, all parallel lines represent due east and due west. Along the latitude, along the earth's rotation direction is due east, and vice versa. Because weft is a weft loop, a closed circle with no head and no tail, and the east-west direction is infinite. In other words, along the earth's rotation direction and along the latitude, it will always be eastward, with no end; On the contrary, if you keep going against the latitude of the earth's rotation, you will keep going west, never ending.
