In the textbook it mentioned "Dou Yan-Shan was a righteous man. He was known for teaching his five sons well." The education method of the ancients varies, and Dou Yan-Shan's education method is an example for everyone. Dou Yan-Shan was rich and unkind in his early years. Besides that, he used his power to suppress the poor and had always been childless. With increasing age, he repented, restrained himself and benefited others and maintained good relationship with them. The couple then had five sons. Dou Yan-Shan educated his sons by making himself for an example for his sons. He persisted for decades so his sons are all righteous and outstanding. They successively passed the imperial examination and all held important positions. Canglong is a metaphor for Dou Yan-Shan, emphasizing the importance of teaching by being the example oneself, expecting the children grow up to be outstanding, and praising the father's selfless love for his children. https://live.staticflickr.com/65535/51844573522_f94a4c19e1_c.jpg
