Does Master Shen, the best bride, know that Gu Xiangping is not good?

In "The Best Bride", Shao Meiqi plays Gu Xiangping as a black-hearted and heartless Shen family girl. She is the hostess of Shenjiazhuang. She looks affectionate and always smiles, but in fact, there is danger and great conspiracy hidden in her extravagance. Tang Doudou has been prevented from finding out Shen Bonan's head injury, because she caused Shen Bonan to become mentally retarded from a prodigy, and the reason why she framed Shen Bonan is actually because she is not really Gu Xiangping, the wife of the boss of Shenyang Zhuang, but Gu Xiangping's sister Gu Xiangru. In order to hide her identity, she killed many people, Shenyang's great-grandfather and Guo's mother. When was she arrested?
