That's too much. Let's talk about the system first: 1, the county system established in the Qin Dynasty has been constantly changing and improving and continues to this day; 2. The imperial examination system was established in Sui Dynasty, and the examination system was implemented according to grades and disciplines. Don't think that the imperial examination really disappeared after 1905. Now the senior high school entrance examination and junior high school entrance examination, as well as master's and doctoral examinations, are not they also based on grades and subjects? 3. The weights and measures system, "the same language" and "Mandarin" promoted by the Qin Dynasty. All dynasties have unified writing, language and weights and measures. For example, the simplified Chinese characters, Putonghua and kilogram scales we use now were gradually improved and implemented after the founding of New China.
Secondly, legal culture. In fact, the law has been handed down, but it has been modified differently according to the ideas of the ruling class. However, to say that it has far-reaching influence, it is still Shang Jun's book and a brief introduction to the Tang law. Among them, Shang Jun seems to be the earliest extant work embodying the rule of law, while Tang Law is regarded as the representative of Chinese legal system, one of the five legal systems in the world, which has a far-reaching influence in the legal history of China and Southeast Asia. When I heard about the laws of New China, there were many references to the laws of the Tang Dynasty.
