Sun Shangxiang in Romance of the Three Kingdoms, why did she take Adou back to Soochow?

Let's talk about why Sun Shangxiang left Liu Bei, because only leaving Liu Bei will take Liu Chan away.

In the winter of the thirteenth year of Jian 'an, as we all know, Sun Liu's allied troops defeated Cao Cao in Chibi. A year later, in the winter of the 14th year of Jian 'an, Sun Quan married his sister Sun Shangxiang to Liu Bei. At this time, Liu Bei was forty-nine years old and Sun Quan was twenty-nine. Forty-nine, less than twenty. Liu Bei is not the kind of person who values sex over friends. In the troubled times when brothers are like brothers and wives are like clothes.

If he had to choose between his wife and his brother, he would definitely choose his brother. There is a simple reason. If you don't have a wife, you can find another one. If you had the power, would you marry a wife? But his brother is the capital of his farmland. If his brother is gone, what capital does he have? Therefore, a capable brother is more precious. From the subsequent contact, I can see that Sun Shangxiang may be abandoned at any time. Because of this, she intends to leave Sun Quan and take Adou Liu Chan with her when she leaves. Why?

In the fifteenth year of Jian 'an, the relationship between Liu Bei and Sun Quan split. When Liu Bei left Jingzhou for the Western Expedition, he entrusted the military and political affairs of Jingzhou to Guan Yu, Zhang Fei and Zhuge Liang, and also entrusted the police of Sun Shangxiang and Adou to Zhao Yun. Because Liu Bei stayed in Sun Shangxiang to raise his only son when he entered Shu, but formally because of this arrangement, when Sun Shangxiang decided to return to Jiangdong, he wanted to take Adou with him.

Some people say that Mrs. Sun's intention to take Ah Dou away is malicious, perhaps because she wants to keep Ah Dou hostage in Jiangdong and intimidate Liu Bei, a subordinate of Sun Quan. Actually, it's not like this. Although Adou Liu Chan was not born in Sun Shangxiang, women are always born with motherhood and love children. Besides, she never gave birth to a child herself, but she raised Liu Chan for two years without hesitation, and established a mother-child relationship with each other, which is why Sun Shangxiang wants to take Adou away.

When Sun Shangxiang took Liu Chan away, Zhao Yun, who looked after them, failed to stop him, so he had to run to find Zhang Fei. Together, they took the path to catch up. They were stopped on a boat by the river and asked why they left suddenly. Sun Shangxiang said; My mother is seriously ill at home. If I wait for your big brother to come back, it will be too late. If you don't let me go today, I would rather die in the river. Zhang Fei didn't agree, so Zhao Yun advised Zhang Fei that we should just take the young master back and not force his sister-in-law to death.

Sun Shangxiang had to hand over Liu Chan, because in that troubled times dynasty, if Sun Shangxiang didn't agree, Zhang Fei would not hesitate to kill her. Liu Beizhong's brother has no feelings for his wife, and it's okay to go back and get scolded at most. If Sun Shangxiang took away Liu Chan and Liu Bei had no heir, what's the use even if he made a great career?
