Immediately, Liu Bei sent Chen Zhen (Liu Bei’s good friend) to deliver a letter to Guan Yu. Chen Zhen (also Yuan Shao’s General) managed to deliver the letter to Guan Yuan on that night. He told Guan Yu that Liu Bei wanted him to hurry to He Bei and reunite with him.

Guan Yu was so happy to hear about the news that his brother was still alive. He decided to say farewell to Cao Cao and depart as soon as possible. He’ll fight whatever he can if Cao Cao refuses to let him leave.

The next day morning, Guan Yu went to see the Prime Minister. Guan Yu stay in front of Cao Cao’s gate and ask for permission to see him.

However, Cao Cao did not entertain him at all. Thus, Guan Yu when to Zhang Liao’s house to ask for help. Guan Yu received the same response as when he reached Zhang Liao’s house. There was an Avoiding Guest Plank hanged upon a locked door. This meant Zhang Liao refused to see visitors.

Guan Yu returned to Cao Cao’s residence every day, but Cao Cao always refused to see him. Cao Cao’s avoidance tactic seems to be very effective at first.

One day, Guan Yu ordered his assistant to sweep his entire mansion clean. He also ordered to take out all things that the Prime Minister gave him and return to him. He told Liu Bei’s wife that they will leave that afternoon.

Meanwhile, Guan Yu was worrying whether he can reach He Bei smoothly because He Bei is 1,000 miles from the capital. Before he departed, he asked his assistant to deliver a farewell letter to Cao Cao since Cao Cao keep on refusing to see him. After Cao Cao received the farewell letter, he immediate rushed to Guan Yu’s direction to send him off. Cao Cao aware that avoiding seeing Guan Yu was his fault and he shouldn’t break his promised. He sent some gold to Guan Yu as to farewell with him. That’s the end of the relationship between Cao Cao and Guan Yu.

In order to go He Bei, Guan Yu needs to past 5 Gates. At each gate Guan Yu will go through, there’s someone waiting for him.
