Why are rng and edg called pig-dog war?

Because there is a factory director who plays with sister pig, and UZI, nicknamed "puppy".

RNG and EDG, as long as you look at LPL, no one does not know these two teams. Even in 2020, RNG team will still rank first in LPL team, and EDG may not be as good as before, but it still has a high popularity.

Only because RNG team has UZI and EDG team has Ming Kai. UZI is also known as a puppy, and the factory director is also known as a pig farmer, so the competition between RNG and EDG is usually called the pig-dog war. These two teams can be said to be the glory of LPL, but now they have become a joke of LPL.
