Regarding Longshan culture, I think it is fortunate that I found it early. At that time, foreigners somehow got the conclusion that the ancient Chinese culture was introduced from the West. Therefore, Longshan excavation, the central government and the Shandong provincial government at that time attached great importance to the central government in the last 30 years. An archaeological organization headed by Fu Sinian was established and the conclusion of ancient culture found in the middle and lower reaches of the Yellow River was reached.
