In Shanghai during the Republic of China, wars were raging and the cultural context was in turmoil. Chu Nian'an, a family of antique connoisseurs and collectors, was good at distinguishing gold, stone and ancient paintings, and had a pair of keen eyes to detect forgeries in the world; Bluebird Inspector He Huaili took charge of the secret line and traveled around to track down cultural relic thieves. When the two first met, they were suspicious of each other and tried every step of the way. However, they were forced to walk side by side in dangerous situations one after another.
Purpose: Instead of the People's Republic of China's espionage war and power plotting, they ran around and picked up national treasures in the Republic of China.
