Lantern relation is a way to show the relationship between two people, similar to how two lanterns shine their light on each other. Imagine you and your best friend each have a lantern. If you face each other and turn on your lanterns, the light from your lantern shines on your friend's face and the light from your friend's lantern shines on your face. This is like a lantern relation, because you both have an influence on each other, just like the light from the lanterns.
In the same way, people can have a lantern relation in real life. It describes a relationship where two people have a significant impact on each other, which can be positive or negative, like the light from the lanterns being bright or dim. One example of a lantern relation could be a teacher and a student. The teacher has a significant impact on the student's education, while the student's performance can also have an impact on the teacher's job.
Overall, a lantern relation is like two lanterns shining on each other, representing the back-and-forth influence two people have on each other in a relationship.
