"National Treasure in the Mist" is a modern urban legend that combines antique treasure appraisal, suspense adventure and family feud. The story begins with an ordinary live broadcast by Chen Xing, a young treasure appraisal anchor, but he becomes involved in a mystery that spans seventy years because of a Qianlong blue and white plum vase displayed by a mysterious woman. This plum vase, which involves a huge amount of gold and a bloody past, reveals the mystery of the bizarre theft and fire in the Chen family's "Chengde Dang" on the eve of liberation. On the way to pursue the truth, Chen Xing encountered the pursuit and temptation of the antique smuggling group "Zhuang", and formed an alliance with Zhou Sui, a female police officer from the Guangzhou Customs Anti-Smuggling Bureau. From the old house in Guangzhou to the Humen Caves, from the old warehouse in Huangpu to the desert of Los Angeles, a life and death battle surrounding national treasures, gold and family honor unfolds fiercely in the interlacing light and shadow of the Guangdong-Hong Kong-Macao Greater Bay Area. The work not only depicts the twists and turns of the antique world, but also explores the weight of history and individual choices. It is a suspenseful masterpiece full of cultural heritage and modern rhythm.
