When will Guan Yu escort Liu Bei's wife out of Cao Daying?

Suddenly remind of a joke and share it with the landlord:

What can be inferred from the following five independent events?

1. Guan Yu left Cao Ying safely with two sisters-in-law;

2. Zhao Yun went in and out seven times to save the sinus, and Cao Cao said no arrows.

3. When Zhao Yun handed Adou to Liu Bei, Liu Bei threw Adou to the ground;

When Liu Bei died, he told Zhuge Liang that Adou could help him, and if he couldn't, he would take his place.

5. Wargo destroyed Shu and surrendered happily in Kaesong.

What conclusion did the landlord draw?
