Lady Sun. You can find basic information about her life in her archive file here, so I won’t go into that. This is intended as a supplement to what everyone already knows. This is new information I got from Notable Women of China.
Anyways, just a little bit on her. I don't elaborate much, but if you start from reading my previous posts on women you should be able to start analyzing facts on your own without me spoonfeeding.

Information about the Sun’s family background can be found in de Crespigny’s online works concerning the Sun family. A summarization goes that the Suns had been minor local officials and were established in their community, but outside of that not too influential until Sun Jian was distinguished starting with his fight against the Yellow Turbans. From there, he attempted to marry rather higher up to the Wu family after hearing of Lady Wu’s ‘beauty and talent.’ Because of his lower social status they were reluctant, but Lady Wu successfully argued her case, telling them that it was better to gamble off a daughter than risk the consequences should Sun Jian rise and remember this slight.
Lady Sun herself was born probably in Kuaji. In 189, Sun Jian left his position as Administrator of Changsha to join the coalition against Dong Zhuo, Lady Wu took herself and their children easy to Lujiang to live with Zhou Yu’s family, and when Sun Jian died, to Guangling.
She was married to seal an alliance between Sun Quan and Liu Bei in 209.
How was she during this time? de Crespigny writes, "she took general control of Liu Bei's household, and she
exercised guardianship over his infant son and heir Liu Shan" (Gen. of the South, Warlord State).
This biography of women makes the claim that Lady Sun made a separate home from Liu Bei five miles from Gongan. It uses the word city, which makes it highly doubtful that she would be allowed the resources to establish an entirely new town. Although primary wives were in charge of the household and managing its expenditures and finances, including development of property and investment, it would be unlikely that she could have built a whole new city right under the nose of the Shu government. However, it would not be surprising or inappropriate if she and Liu Bei lived separately, as their loyalties lay in opposite directions. This is not an unusual arrangement for married couples would could not tolerate one another. In fact, considering the political tensions between the two, especially as the alliance began to fracture, it would have been mutually beneficial to live separately. I would think that Zhuge Liang would have wanted her under watchful eyes, though, so I would think it more realistic that she merely lived in a separate house in the capital city. But I have no way of knowing.
In 215, due to Liu Bei’s capture of Yizhou the alliance fell apart. Whether of her own initiation or by Sun Quan's coaxing we do not know, but she kidnapped Liu Chan and attempted to make her way back to Wu. However, she was stopped by Zhao Yun and Zhang Fei. However, she was allowed to return back to Wu.
About her as a person. She kept a group of armed maids (retainers). This is in no way shape or form normal for this time period. Women were not taught to fight, and it probably would have been frowned upon, as it definitely went outside the inner quarters. Even in times of rebellion and the such there was no significant effort to arm women to even protect themselves. For this time period, this was extremely, extremely unusual, to the point of having to interpret her actions and traits from the perspective of a man instead of a woman.
Liu Bei was said to have been scared of her to the point that he was frightened in his own home. [spoiler]A married woman lives in her husband's home.[/spoiler] Zhuge Liang himself regarded her as a potential source of a coup. This should say something about her ability and strength.
The text provides the following information, but except for the Embroidery Forest part, I highly doubt the rest of them and would consider them folklore-based embellishments. “The Embroidery Forest Moutainn, 2 miles southwest of the Shishou county in Hubei province, is where Liu Bei married Madam Sun. It was so named because, in Madam Sun’s eyes, the forest looked as if it were made of many sheets of beautiful silk.
