It is not true that the Koryu Dynasty ruled during a long period of Mongol occupation.

Explanation:

The Koryu Dynasty governed the Korean Peninsula from 918 to 1392. It was founded by King Taejo in 918 on the ruins of the united bridge, and later spread to most parts of the Korean Peninsula. During that period, Korea began to develop a cultural tradition distinct from the rest of East Asia. The Mongol Empire subdued the Kingdom in the 13th century and its ruler family became Mongolian, but retained its formal independence. As the Mongolian Yuan Dynasty ruled China, Koryu's rule began to weaken and in 1392 General Seonggye led a peaceful coup that led to the establishment of the Joseon Dynasty, which ruled Korea until 1910.
