Education is a slightly abstract noun! The so-called level is not a person or unit, but refers to the educational achievements of society or a certain region, people's average knowledge level and moral level! No matter whether the area with high cultural level is prosperous or not, the atmosphere is positive! This is hard to describe for the time being. Cultural level also refers to the average cultural depth and advanced level of education of all citizens. (The above is just my personal understanding, and friends can refer to it. )
