Guo Ziyi and Li Guangbi united against the enemy.
During the reign of Emperor Xuanzong of the Tang Dynasty, Guo Ziyi and Li Guangbi were subordinate ministers of Ansishun. The two have contradictions and don't talk much at ordinary times. Later, during the Anshi Rebellion, Guo Ziyi was promoted to our northern province, and he took all the troops to fight. Li Guangbi became the ministry of Guo Ziyi. The emperor ordered Guo Ziyi to take part in the war, and Li Guangbi was worried that Guo Ziyi would use his power to retaliate. Li Guangbi crustily skin of head to Guo Ziyi said, "it's my fault, I offended you in the past. No matter what I do in the future, I have no complaints. I just hope to spare my wife and children ... "Before Li Guangbi finished, Guo Ziyi hugged Li Guangbi tightly and said with tears," The country is in crisis and the people are suffering. We need to work together. At this time, we need talents like you. How can you care about personal grievances? "
