Based on the information given, I recommend the novel "Reborn Cute Wife Has Space" to you. Although the female protagonist's name was not Cang Qiong, the female protagonist and her brother both had special abilities. The female protagonist had spatial abilities, while her brother could predict the future, which was consistent with the description in the question. This novel involved love and relationships with wealthy families. It was about the sweet love between the female protagonist and her male protagonist, Si Jinhan. I hope you like my recommendation.
