[2] Korean historical records say that Micheon fled and hid as a servant in a miserable life, doing menial tasks such as throwing stones into a pond throughout the night to keep his master from being awakened.

During the disintegration of China's Jin Dynasty,[5] he expanded Goguryeo's borders into the Liaodong Peninsula and the other Chinese commanderies.

[6][10] In his reign, Goguryeo was faced with growing Xianbei influence in the west, particularly the Murong tribe in Liaodong.

[5] [6] Since both sides were at stake, Micheon sent an ambassador to the Later Zhao dynasty in 330 with a view to making a diversion against the Murong.

[6] Twelve years later, in the reign of King Gogugwon, his remains were dug up by the Former Yan invaders, and held for ransom.
