What does 3: 1 mean?

Three points and one line indicate that life is single and describe the unchanging life.

Every day is to go to work, get off work and go home. This kind of life is called 3: 1. Go to school, leave school and go home. This kind of life is also called 3. 1 line. Dormitories, offices and canteens are also 3: 1.

The unchangeable life is a stagnant pool, without vitality, without the fun and freshness of life, retrogression and progress. This kind of life will easily enter a fixed cycle, which seems comfortable, but in fact it is undercurrent.

The basic meaning of three points and one line:

Three points and one line in the management mode: it is a simple and effective new management mode that has been proved by repeated practice. It is a hotel platform management driving system composed of guarantee framework, decision-making traction framework, incentive driving framework (three points) and marketing (first line).

The sun, the moon and the earth are three points and one line:

There are only two times in a year when the sun, the moon and the earth are on the same plane, that is, when the moon passes through the intersection of the ecliptic and the descending node. When there is a solar eclipse or a lunar eclipse, the three are in a straight line.

If the earth is between the sun and the moon, it is called an eclipse, and the moon is between the earth and the sun. As for the fact that the three are on the same straight line, the probability is even smaller. It is only possible when the moon passes through the ecliptic and descending node, and it happens to be the new moon and the full moon. If the three are strictly on the same straight line, the probability is ignored.

Three point one line is a mathematical theory. The concept is that three points are on the same straight line, or some three points can form a straight line. A straight line is composed of countless points, which is a part of a surface and then constitutes a body. A straight line is an axisymmetric figure.

Example: four-point PABC on the plane satisfies PC=xPA+yPB, x+y= 1. It is proved that ABC's three points and one line PC = XPA+YPB = (1-y) PA+YPB = PA+Y (Pb-Pa) = PA+YAB, that is, PC-PA=yAB.
