In the mid of San Kuo, Wei, Shoo, and Wu Era, Shoo and Wu were in danger due to the ambitious and strong power of Wei.

Liu Bey paid three humble visits to Ju Kot, an helmet on the mountain though opposing by his generals, Kwan Yu and Chang Fei and invited Ju Kot as adviser.

Ju Kot advised uniting with Wu to fight against Wei so Liu Bey appointed him for that. While Cao moved his armies to Chi Bei, which threatened Wu and Shoo. Suen Chuan of Wu also adopted Ju Kot’s proposal.
