Ma Xiaodong invented the health code and provided it to this country for free. What unsung heroes do you know?

Sima Cuo and Lou Jing.

In real life, there are always some unknown people working hard. They have made outstanding contributions to the construction of the motherland and the development of all walks of life. Although they have not become well-known public figures, people can't ignore their efforts. During the epidemic, countless unsung heroes devoted themselves to the fight against the epidemic. Ma Xiaodong invented the health code, but decided to donate it for free.

In history, many heroes have promoted the development of history. Although the popularity is not high, it can play a vital role. There are too many unsung heroes, and Sima Cuo and Lou Jing are two of them.

Sima Cuo became an important logistics personnel in Qin Jun. Although there are many heroes on the battlefield, people can't ignore the efforts of logistics personnel. Sima Cuo is not well-known in history, but he has unique skills. At that time, Sima Cuo used this technology to successfully ensure the logistics supply of the Qin team. Some people may think that the importance of Sima Cuo is negligible, but it is not. It was the efforts of logistics personnel one after another that made the Qin Dynasty complete the process of unification.

Lou Jing invented affinity, which laid the foundation for many dynasties to establish a good social order. Whether in the Tang Dynasty, where the economy was very prosperous, or in the Song Dynasty, where the development was particularly rapid, there would be affinity. In order to consolidate the frontier fortress or establish good relations with consorts, the central rulers will send princesses to get married, such as Princess Wencheng. Lou was close to the inventor, and since then, many rulers of dynasties have used the core to consolidate the central government, providing favorable conditions for the establishment of a unified system.

Although the popularity of unsung heroes is far lower than that of celebrities, their achievements are not lost. However, there are few records of unknown people in historical records, so people can't get a lot of information, and film and television works will not use a lot of space to describe relevant people.
