People's Education Edition (Compulsory 2) There is a picture named "Niu Geng Portrait Stone" in history, which reproduces the labor scene of "two cows competing for the front" in the Eastern Han Dynasty. This picture can bring us at least three messages. First of all, this picture is an important material evidence to show that more advanced farming methods than coupling farming appeared in Han Dynasty. Secondly, this relief stone was unearthed in Mizhi area in northern Shaanxi, which is relatively far from the Central Plains, which also shows that the advanced farming method of "two cows carry the burden" has been widely spread at that time. In addition, this portrait carved on brick and stone has a complete composition, outstanding key points, and the shapes of figures and animals are very realistic, which also reflects from the side that the carving art in the Eastern Han Dynasty reached a high level. This is a vivid example of historical truth. By studying these pictures carefully, we have a better understanding of the progress of agricultural technology in this period. At the end of the Western Han Dynasty, the farming methods of two cows and three people were gradually replaced by the farming methods of two Niu Yi people.

In a word, pictures play an important role in history education and are also important materials for making test questions. Therefore, we should conduct targeted research on this topic in history teaching, so as to urge students to think carefully and appreciate the information contained in pictures, thus improving the effectiveness of history classroom teaching.
