Behind every national treasure-level cultural relic, there is a little-known story, and the bronze weapon with sword cast in the Spring and Autumn Period, Soldiers Lost in Public Service, is no exception. On June 28th, 2006, a villager column in a village in southwest Henan accidentally found a treasure under an excavator. Pillars don't have much culture, but cultural relics are valuable, and pillars still know something. So, Zhuzi rushed to Beijing overnight with her child in her arms, and found Bao Chunlin in the same village. Bao Chunlin wandered around the Taobao market in Beijing for many years and knew some cultural relics dealers. Boss Liang is one of them. Boss Liang got the treasure brought by the pillar and identified it as a green steel weapon cast in the Spring and Autumn Period, named "the soldier who lost his job". In the past, someone asked Boss Liang to find "the soldiers don't know the crowd", but now "the iron hoof has been broken", so Boss Liang naturally can't let go easily. In the face of boss Liang's constant price increase, Bao Chunlin and Zhu Zi finally agreed to make a deal with 2.5 million cash.

The cunning boss Liang used the package switching plan in the transaction, so that Zhu Xi and Bao Chunlin took out the "soldiers who lost their jobs" and got a bag of waste newspapers. The deceived pillar was seriously stimulated mentally, but Bao Chunlin, who was extremely angry, was persuaded by Boss Liang because of the temptation of 5 million yuan. Bao Chunlin listened to Boss Liang's words, took100000 yuan from Boss Liang, and sent the pillar back to his hometown in Henan through cajoling. Knowing that the treasure of the town and village was cheated away in Beijing, the oldest third master in the village flew into a rage. In front of the furious Third Master, Bao Chunlin promised to go back to Beijing to find "soldiers who lost their jobs". There is a young man in the village named Huang Dajiang who works as a lawyer in Beijing. At first, Huang Dajiang didn't want to participate in this matter, but when Sanye personally arrived in Beijing, Huang Dajiang found that there was no way to participate.

The plan to win the treasure planned by Huang Dajiang and his girlfriend Lili is full of drama. When Bao Chunlin, Zhu Zi, Huang Dajiang and Lili disguised themselves as property security guards, cleaners, electricians and plumbers respectively, they took the opportunity to come to Boss Liang's house to implement the plan to recapture the soldiers who lost their jobs. Mr. Yamada, a Japanese guest contacted by Boss Liang, came to Beijing at the invitation of Boss Liang.

September 18, 2006 was the day when boss Liang and Mr. Yamada made a deal. At this time, Boss Liang and Mr. Yamada never imagined that Bao Chunlin, Huang Dajiang and others who were determined to recapture the "soldiers who lost their jobs" had already been arranged by their side. In the chaos caused by an "unexpected" traffic accident, Bao Chunlin and Huang Dajiang got their wish and regained the "soldiers who lost their jobs". At the celebration banquet in his hometown, under the persuasion of Huang Dajiang and Lili, Sanye finally sent the "soldiers who disappeared in front of the public" to the Beijing Museum, so that more people could understand the history of "soldiers who disappeared in front of the public".
