It says two things. Why did you describe Chen Yaozi's archery in detail when the old man was cooking oil? (oil seller)

This paper focuses on archery and oil transportation, because familiarity can achieve superb skills, rather than Chen Yaozi's archery. Therefore, Chen Yaozi's Archery only uses four words, which is very short. This is simple and appropriate, highlighting the key points of the article.

The detailed arrangement of this article is to describe the characters and express the needs of the center. Weng's superb oil selling skills highlight in details that he convinces people by reasoning and wins each other's image by "transporting oil" skills. Chen Yaozi's shooting skill is only briefly described by "nine times out of ten", while his arrogance is described in detail. Highlight their respective personalities, and the center of the article is also very prominent.
