According to reports, 248 middle schools in a poverty-stricken area have had classes synchronusly with key middle schools in a certain tier city through live broadcasts for 16 years  In the past 16 years, some of these 248 middle schools have turned out provincial champions, and some have raised the undergraduate enrollment rate more than ten times  From the data point of view, this live teaching model is very successful
However, it is regrettable that this successful model has not been widely promoted across the country
Different middle school students have different knowledge bases, so that this kind of live teaching lacks pertinence.
